Abstract
The intimate mechanism of the one pot synthesis of chrysanthemic esters from methyl 4-oxo-butenoate and phosphorus ylide is disclosed. The first equivalent of ylide reacts selectively on the aldehyde function and the cyclopropanation occurs on the preformed betaine prior to its decomposition.
