Jeong, Yun-Kyung published the artcileIntramolecular hydroalkoxylation in Bronsted acidic ionic liquids and its application to the synthesis of (±)-centrolobine, Computed Properties of 86549-27-1, the main research area is sulfonic acid substituted triazolium imidazolium ionic liquid preparation; cyclic ether preparation; racemic centrolobine stereoselective preparation; hydroalkoxylation unsaturated alc sulfonic acid substituted ionic liquid catalyst; stereoselective cyclization unsaturated alc sulfonic acid substituted ionic liquid; Bronsted acidic ionic liquid preparation catalyst stereoselective cyclization.
Sulfonic acid-substituted triazolium and imidazolium ionic liquids such as I·CF3SO3- (X = N, CH) are prepared; I·CF3SO3- (X = N, CH) act as catalysts for the cyclization reactions of alkenyl alcs. such as HOCH2CMe2CH2CH:CH2 to give cyclic ethers such as 2,4,4-trimethyltetrahydrofuran. (±)-Centrolobine II (R = H) is prepared using the stereoselective cyclization of III to II (R = PhCH2) in the presence of I·CF3SO3- (X = N or CH) as the key step; III is prepared in three steps from p-anisaldehyde and 4-benzyloxyphenylethyl bromide. I·CF3SO3- (X = N) can be used three times for the cyclization of 2,2-diphenyl-4-penten-1-ol to 2-methyl-4,4-diphenyltetrahydrofuran.
Organic & Biomolecular Chemistry published new progress about Cyclic ethers Role: SPN (Synthetic Preparation), PREP (Preparation). 86549-27-1 belongs to class esters-buliding-blocks, name is Ethyl 2,2-dimethylpent-4-enoate, and the molecular formula is C9H16O2, Computed Properties of 86549-27-1.
