Abstract
Abstract Functionalised enanines constitute a category of synthetic intermediates useful in carbon, carbon bond formation reactions and have been procured through a variety of condensaticn and extrusion reactions.1 In one approach active methylene compounds have been condensed with lactin thioethers in the presence of a base at relatively higher temperature.2,3 In view of our interest in the synthesis of function alised enamines through sulphur extrusion reactions4, we have studied the title reaction under non-hydrolytic solid-liquid PTC using solid KF(base)/TEBA(catalyst). A recent report5 on the sulphur extrusion of α -thio-iminium salts and their reactions with active methylene compounds prompts us to report our results.
