Diastereotopic Group Selective Intramolecular Conjugate Addition of 4-(2-Hydroxyethyl)-p-Quinol Derivatives: Synthesis of the Optically Pure cis-7-Oxabicyclonon-2-en-4-one Skeleton.

Article abstract of DOI:10.1016/S0957-4166(00)86199-6

Diastereotopic group selective cyclization of 4-(2-hydroxyethyl)-p-quinol derivatives was achieved and the reaction applied to the synthesis of the optically pure cis-7-oxabicyclo<4.3.0>non-2-en-4-one skeleton.
