Abstract

Przedmiotem wynalazku jest sposób wytwarzania nieracemicznych estrów kwasów karboksylowych o wzorze ogólnym I, w którym n oznacza 1-5, lub zero, R1 oznacza C1-C12 alkil, a R2, R3, R4 oznaczają niezależnie od siebie atom wodoru, podstawioną lub nic grupę hydroksylową, podstawioną lub nie grupę aminową, lub prostą lub rozgałęzioną grupę C1-C20 alkilową posiadający lub nie wiązanie podwójne lub potrójne, aryl. Zastosowanie racemicznych kwasów karboksylowych i prowadzenie reakcji do uzyskania 100% konwersji substratu umożliwia uzyskanie enancjomerycznie czystych estrów z wydajnością do 100% posiadających nadmiar enancjomeryczny > 99,5%.The subject of the invention is a process for the preparation of non-racemic esters of carboxylic acids of the general formula I, in which n is 1-5 or zero, R1 is C1-C12 alkyl, and R2, R3, R4 are independently hydrogen, substituted or nothing by hydroxyl group , substituted or not amino group, or straight or branched C1-C20 alkyl group with or without double or triple bond, aryl. The use of racemic carboxylic acids and carrying out the reaction until 100% conversion of the substrate allows obtaining enantiomerically pure esters with a yield of up to 100% having an enantiomeric excess > 99.5%.
