EXAMPLE 11 Methyl alpha-formylsuccinate In a modification of the procedure of Fissekis and Sweet, Biochemistry 1970, 9, 3136-42, sodium methoxide (40.5 g, 0.75 mol) was suspended in dry ether (500 mL) and stirred under nitrogen at 0 C. A mixture of dimethylsuccinate (65.4 mL, 0.50 mol) and methylformate (123 mL, 2.00 mol) was added dropwise over 30 minutes. The reaction mixture was stirred at 0 C. for 2 hours and then at room temperature overnight. Subsequently, the reaction mixture was evaporated to a viscous brown residue which was washed once with petroleum ether and then dissolved in 3 M hydrochloric acid (160 mL). This solution was made weakly acidic with concentrated hydrochloric acid and then extracted with dichloromethane (4*250 mL). The organic phase was dried (MgSO4), filtered and evaporated under reduced pressure. The resulting residue was distilled in a kugelrohr apparatus at 60 C. and 0.6 mBar yielding 52.3 g of a mixture of the title compound and dimethyl succinate in the molar ratio 80:20 (determined by NMR) as a colorless oil. This mixture can be used directly in the following preparation. The product can be isolated free of dimethyl succinate by exchanging the extraction with dichloromethane with a continuous extraction with diethyl ether. However, in our hands this reduced the yield to 34%. Fissekis and Sweet,ibid, had reported a 62% yield. 1H-NMR (DMSO-d6/TMS): delta=3.20 (s, 2H, CH2); 3.59 (s, 3H, OMe); 3.61 (s, 3H, OMe); 7.73 (s, 1H, CHOH); 10.86 (br s, 1H, CHOH). 13C-NMR (DMSO-d6/TMS): delta=28.9 (CH2); 51.0 (OMe); 51.6 (OMe); 102.1 (C=CHOH); 156.6 (CHOH); 168.3 (COO); 171.7 (COO).

Cholesterol in the Viral Membrane is a Molecular Switch Governing HIV-1 Env Clustering

HIV-1 entry requires the redistribution of envelope glycoproteins (Env) into a cluster and the presence of cholesterol (chol) in the viral membrane. However, the molecular mechanisms underlying the specific role of chol in infectivity and the driving force behind Env clustering remain unknown. Here, gp41 is demonstrated to directly interact with chol in the viral membrane via residues 751-854 in the cytoplasmic tail (CT751-854). Super-resolution stimulated emission depletion (STED) nanoscopy analysis of Env distribution further demonstrates that both truncation of gp41 CT751-854 and depletion of chol leads to dispersion of Env clusters in the viral membrane and inhibition of virus entry. This work reveals a direct interaction of gp41 CT with chol and indicates that this interaction is an important orchestrator of Env clustering.

Divergent functionalization of terminal alkynes enabled alkynylative [5+1] benzannulation of 3-acetoxy-1,4-enynes

We here describe an alkynylative [5+1] benzannulation of 3-acetoxy-1,4-enynes with terminal alkynes, which enables both the construction of a benzene ring skeleton and intermolecular incorporation of an alkynyl group in a single reaction using Pd and Cu cooperative catalysts. The method represents efficient access to internal aryl alkynes through divergent functionalization of two terminal alkyne components: one alkyne serves as the one-carbon unit to realize the [5+1] benzannulation and the other alkyne as a nucleophile terminates the reaction.

Thin layer chromatography based extraction approaches for improved analysis of volatile compounds with gas chromatography-mass spectrometry and direct analysis with gas analyzer

In this study, thin-layer chromatography was applied for selective extraction of volatile compounds in perfume prior to analysis with solid phase microextraction and gas chromatography-mass spectrometry. The standard compounds were desorbed from the thin-layer chromatography plate and extracted at 80 degrees C for 15 min showing good linearity of the calibration curves (R-2 > 0.98) and acceptable recovery range (65-81%). The plate after the separation was cut into four smaller parts followed by solid phase microextraction/gas chromatography-mass spectrometry analysis, which revealed different compound profile in each part with the correlation between log P of the standard compounds and their positions along the thin-layer chromatography plate (R-2 = 0.65). This approach was applied to analyze perfume compounds in the sample with strong matrix interference from the synthetic agarwood. Terpene hydrocarbons (woody-based odors), ketones/esters, aldehydes, ethers, and alcohols were mostly observed at 8 +/- 1, 6 +/- 1, 5 +/- 2, 4 +/- 2, and 3 +/- 2 cm, respectively, from the bottom of the thin-layer chromatography plate. While, the conventional solid phase microextraction/gas chromatography-mass spectrometry analysis of this sample solution revealed only 62 compounds (including 35 perfume compounds), the four-piece approach resulted in 109 compounds (62 perfume compounds). Furthermore, the capability of thin-layer chromatography-Gas Analyzer approach to analyze the isomers in this complex sample was demonstrated.

Synthesis of functionalized cyclopropylboronic esters based on a 1,2-metallate rearrangement of cyclopropenylboronate

A procedure converting tribromocyclopropane to densely functionalized beta-selenocyclopropylboronic ester using the 1,2-metallate rearrangement of a boron ate-complex has been developed. Treatment of an in situ-generated cyclopropenylboronic ester ate-complex with phenylselenenyl chloride triggered stereospecific rearrangement to produce functionalized cyclopropanes. DFT calculations for 1,2-metallate rearrangement suggested that the reaction proceeds through a seleniranium intermediate.

Larval energetics of the Sydney rock oyster Saccostrea glomerata and Pacific oyster Magallana gigas

Larvae are a critical dispersal stage of marine invertebrates, and their survival depends on nutrition and energetics. This study compared the size, survival, metabolic rate and egg and larval lipid class profiles of larvae of the endemic Sydney rock oyster Saccostrea glomerata and the invasive Pacific oyster Magallana gigas through a period of starvation for 5 and 9 d after fertilisation. Starved larvae grew without food until 5 d of age, at which point they stopped developing, but resumed growth when fed. Egg lipids profiles comprised 78.1 and 74.5% triacylglycerol for M. gigas and S. glomerata respectively. When fed, larvae of M. gigas were significantly larger in size and had faster growth and similar survival compared to S. glomerata. When starved, larvae of M. gigas and S. glomerata grew at similar rates, and there was a trend for lower survival of M. gigas. Larval endogenous lipid reserves were deleted in the first 24 h. Larvae of M. gigas had more total lipids and comparatively more diacylglycerols, monoacylglycerols, phospholipids and cholesterol, whereas S. glomerata had more diacylglycerols and produced sterol esters. Starvation altered the patterns of lipid assimilation, and metabolic rates of larvae of M. gigas and S. glomerata differed over time. When starved, S. glomerata larvae had greater capacity to cope with starvation compared to M. gigas, perhaps due to an evolutionary history in oligotrophic estuaries. As the climate rapidly changes in this global climate-change hotspot, S. glomerata is likely to be negatively affected.
