标 题:Enzyme-mediated synthesis of esters and lactones
发明人：GATFIELD IAN; SAND THEODOR
权利人:HAARMANN & REIMER GMBH
摘要:In the enzyme-mediated synthesis of an ester or lactone from at least one carboxylic acid of the formula R-CH2-CH2-COOH wherein R is a hydrogen atom, or a hydrocarbon radical which has 1 to 21 carbon atoms and which can be optionally substituted by hydroxyl groups or alkoxy groups with 1 to 10 carbon atoms, with at least one primary or secondary alcohol having 1 to 15 carbon atoms, the improvement which comprises employing as the enzyme the esterase from Mucor miehei and effecting the synthesis in the absence of water. Advantageously, the synthesis is effected at about room temperature, the mol ratio of carboxylic acid to alcohol is from about 1:1 to 1:1.1, and the enzyme is used in a quantity of about 3 to 20% by weight of the carboxylic acid. The absence of water facilitates recovery, as by distillation.

标题:Asymmetric synthesis of acids by the palladium catalysed hydrocarboxylation of olefins
发明人：ALPER HOWARD
权利人:BRITISH PETROLEUM CO PLC
摘要:A process for preparing a chiral carboxylic acid or ester thereof, either as a single enantiomer or as a mixture of enantiomers in which the presence of one enantiomer is enhanced relative to the others comprises reacting a prochiral olefinic function and either water or an alcoholic function with carbon monoxide in the presence of a protonic acid other than nitric acid, a single enantiomer of an optically active compound chosen from the class of chiral phosphoric acids or derivatives thereof, and a catalyst comprising (a) at least one of the metals palladium, rhodium, ruthenium, iridium and cobalt and (b) copper. A preferred class of optically active compounds comprises either the (S+) or the (R-) enantiomer of 2,21-(1,11-Binaphthyl) phosphoric acid or its esters or its salts, optionally substituted.
