Chemistry of Dimedone for Synthesis of Oxygen-, Nitrogen-, and Sulfur- Containing Heterocycles from 2-(3-Hydroxy-5,5-dimethylcyclohex-2-enylidene)malononitrile

Abstract

A series of new oxygen-, nitrogen- and sulfur- containing spiro heterocycles was synthesized by reactions of 2-(3-hydroxy-5,5-dimethylcyclohex-2-enylidene)malononitrile with some active methylene and bidentate compounds.
