Synthesis and Diels–Alder reactions of 1-((E)-2-tert-butyldimethylsiloxy)ethylidene-4a-carbomethoxy-1,2,3,4,4a,5,6,7-octahydronaphthalene and related substances. Preparation of functionalized decahydro-1H-phenalenes

Abstract

The preparation of the structurally novel dienes 7 and 8 is described. The results of a study of the Diels–Alder reactivity of these substances and the "parent" diene 9 are summarized and the potential use of the resultant Diels–Alder adducts in organic synthesis is demonstrated.
