accomplished through an organolithium to aldehyde nucleophilic addition. Preparation of the prerequisite key intermediates in optically pure form was based on an improved, short, and efficient synthesis of “wine lactone” from (S)-limonene and Corey’s catalytic enantioselective Diels–Alder reaction of 2,5-dimethyl furan with diethyl fumarate.
