## Abstract The reaction of benzoxathioleβ3βoxide with lithiumdiisopropylamide in tetrahydrofuran gave an anion, which was reacted with various arylβmethylβketones to give 2β(1βhydroxyβ1βarylethyl)β1,3βbenzoxathiolβ3βoxide derivatives. The reaction was carried out in different temperature condition
Simple Three-Component Synthesis of 4-Acyl-5-phenyl-1-(2-hetaryl)-3-hydroxy-3-pyrrolin-2-ones. -Thermal three-component cyclocondensation of methyl acylpyruvate (I), benzaldehyde (II) and hetarylamines (III) furnishes the novel 4-acyl-5-phenylpyrrolinones-2 (IV) containing a hetaryl group at the N(
