Structure Determination of cis- and trans-1, 4Diacetoxy-1, 2, 3, 4-tetrahydronaphthalene

Abstract

The oxidation of 1, 2, 3, 4-tetrahydronaphthalene(tetralin) by Co (II)-Ce(III)-NE4, Br in the presence of acetic anhydride resulted in the formation of 1: 1 mixture of cis- and trans-1, 4diacetoxytetralin(A, B). Their structures were discussed on the basis of 1H- and 13C-NMR spectral data, and finally the structure of B was determined by single crystal X-ray method (Fig.2). This was the first report of structure determination of both of cis- and trans-1, 4diacetoxytetralin.
