A process can prepare a compound having the formula  

Plasticizers, polymer compositions and processes for making the plasticizers

A method of preparing a compound of formula (I): wherein: a first group selected from R, Rand Ris an amino- or N-acylamino monosaccharide moiety, the acyl group having 1 to 6 carbon atoms, or an oligosaccharide chain comprising 2 to 4 monosaccharide moieties, at least one of which is an amino- or N-acylamino monosaccharide moiety; a second group selected from R, Rand Ris a alkanoyl and alkenoyl acyl group having 3 to 40 carbon atoms; and a third group selected from R, Rand Ris hydrogen, the method comprising contacting a monoacylglycerol, the acyl moiety thereof being a saturated or unsaturated acyl group having 3 to 40 carbon atoms, or an activated derivative thereof, with a source of amino- or N-acylamino monosaccharide moiety, or an activated derivative thereof, and, if required, a source of unsubstituted monosaccharide moiety, or an activated derivative thereof, optionally in the presence of a suitable catalyst or activating agent, is described. 

Methods for producing amino-substituted glycolipid compounds

A process for the preparation of a compound can have the formula wherein R, Rand Rare independently selected from hydrogen and acyl groups, wherein at least one of R, Rand Ris a branched chain long acyl group of the formula wherein n is from 9 to 21 and m is 2n, and wherein p is from 0 to 4, wherein the other of R, Rand Rare selected from short acyl groups of the formula wherein q is from 0 to 4; the process comprising the steps of: (1) providing an unsaturated compound having the formula (2) if at least one of R, Rand Ris hydrogen, optionally acylating the compound; and (3a) (i) hydroxylating the unsaturated long acyl group and (ii) acylating the hydroxy long acyl group, or (3b) reacting the unsaturated long acyl group with a carboxylic acid.

Process

The present invention relates to a process for preparing a lactone. The process comprises the steps of reacting an aldehyde with an organic halide in a carbon chain extension reaction to form an alcohol compound comprising a functional group capable of allowing for carbonylation of said alcohol compound, and then reacting said alcohol compound in a carbonylation reaction to form an hydroxycarboxylic acid; and cyclizing the hydroxycarboxylic acid to produce the lactone.
