The intramolecular cyclization of malonic acid allylic esters yields bicyclic cyclopropane carboxylic acid lactones in a phase transfer catalysed reaction. The substituents of the allylic moiety and the reaction temperature influence the diastereomeric composition of the products.
## Abstract A method for the preparation of acid amides by heating an equimolecular mixture of acid and thiourea, is described. The method has been successfully applied to aliphatic monoโ and diโbasic acids, arylโaliphatic acids as well as benzoic acid. The yield has been found to be dependent upon
