Method of preparing optically active cyanohydrin derivatives |
| abstract |
Abstract The invention relates to a method of preparing an optically active cyanohydrin carboxylic acid ester from an optically active cyanohydrin of opposite configuration, wherein said starting cyanohydrin is converted with a carboxylic acid in the presence of a dialkyl azodicarboxylate and a triarylphosphine. The invention also relates to a method of preparing an optically active cyanohydrin of opposite configuration by a subsequent solvolysis of the ester obtained under conservation of the configuration. |
