The preparation of cyclohex-2-ene-1,4-diones
Abstract
Alkyl substituted cyclohex-2-ene-1,4-diones have been prepared by the pyrolysis of the appropriate 2,3,4a,5,8,8a-hexahydro-5,8-methanonaphthoquinones. The stereochemistry of some of these intermediates is discussed and the extension of the synthesis to monoacetals of cyclohex-2-ene-1,4-diones is described.
