A stereospecific synthesis of trans-hydrind-4-en-2-ones
Abstract
A general stereospecific synthesis of hydrind-4-en-2-ones is described in which the 1-mono-ester of a cyclohex-3-ene-1,2-diol is converted by a variant of the Claisen rearrangement into a cyclohex-3-ene-1,2-diacetic acid, which is then cyclised.
