Protecting carbohydrates with ethers, acetals and orthoesters under basic conditions was written by Liang, Yang;Pedersen, Christian M.. And the article was included in Organic & Biomolecular Chemistry in 2021.Category: esters-buliding-blocks The following contents are mentioned in the article:
Chlorinated Et and vinyl ethers are introduced at various positions of carbohydrates. Depending on the relative stereochem., vinylethers, acetals or orthoesters are formed under basic conditions. The products are stable, but are easily deprotected after dechlorination. The scope of the intramol. protection is studied using common pentoses and hexoses. This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3Category: esters-buliding-blocks).
(2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Category: esters-buliding-blocks
