A cooperative indium(III)/silver(I) system for the synthesis of various five‐membered heterocycles, including dihydrofurans, pyrroles, spirolactones, and spiroiminolactones, through the sequential oxidative coupling/annulation reaction of 1,3‐dicarbonyl compounds with styrenes has been developed. Four different heterocyclic systems were successfully synthesized depending on the substitution pattern
Thirty tertiary propargylic carbinols have been prepared by condensing propargyl bromide with ketones. Some of them showed better hypnotic activity than 3-methylpentyn-3-01. The best compound of the series was 1-chloro-2-chloromethylpent-4-yn-2-01 which proved to be a very effective hypnotic with a favourable therapeutic index.
