Abstract
The present invention relates to the synthesis of 2,2-dimethyl-3-(vinyl-2,2-bi-substituted) cyclopropanocarboxylic acids. Said acids are present in the majority of natural pyrethrines and in synthetic pyrethroids. These acids are obtained by the transposition reaction aza-di- pi -methane of a 1-aza-1,4,6-trianic system for which there are disclosed three different synthetic processes. Thereby, precursors are available to obtain pyrethrines and pyrethroids, obtained by a direct and simple process with a high yield.
