Synthesis of Terpenoids. IV. The Use of Kinetic Enolates of some Methyl Ketones For Terpenoid Syntheses

Abstract
In recent years the crossed aldol condensation has becocome a useful synthetic method2, however its use for natural product syntheses has been limited to a few cases3. In this paper we wish to describe the preparation of a number of terpenes based in this reaction, which because of its simplicity represent convenient synthesis for these compounds.
