USE OF ACID ANHYDRIDE ACCELERANTS FOR THE PRODUCTION OF HIGH PURITY POLYOL ESTERS

A method of producing high purity polyol esters comprises reacting a polyol with an excess amount of a linear or branched aliphatic monocarboxylic C3-20 acid to esterify less than the total amount of the polyol present to form an intermediate reaction composition having a hydroxyl value of from 7 to about 50 mg KOH/g. An anhydride of the corresponding linear or branched aliphatic monocarboxylic C3-20 acid is added to the intermediate reaction composition in an amount of from 1 to about 2.5 equivalents of available OH in the intermediate composition to form a reaction mixture. The reaction mixture is heated for 5-30 minutes or until all of the corresponding anhydride has reacted to form a reaction product. The reaction product is then de-acidified. No metal or acid catalyst or bleaching agents are present in any of the above reaction steps at a concentration above about 15 ppm.

Ti-Crossed-Claisen condensation between carboxylic esters and acid chlorides or acids: A highly selective and general method for the preparation of various β-keto esters

Ti-crossed-Claisen condensation between a 1:1 mixture of carboxylic esters and acid chlorides promoted by TiCl4-Bu3N-N-methylimidazole proceeded successfully to give various β-keto esters in good yields with excellent selectivities (19 examples, ～48-95% yield; cross/self-selectivity = ～96/4-99/1). The present method was extended to the condensation between a 1:1 mixture of carboxylic acids and carboxylic esters (six examples, ～70-92% yield; cross/self-selectivity = ～91/9-99/1). To demonstrate the utility of the present two Ti-crossed-Claisen condensations, we performed a couple of efficient short-step syntheses of two natural, representative, and useful perfumes, cis-jasmone and (R)-muscone.
