✦ Synopsis

Cyclobexene (&)-3 is completely stable when treated with ZnC1, in CH2C12, but obviously, it is not stable when butynone is also present. Probably, the proton necessary for isomerisation (see also [ll]) originates from the complex between butynone and ZnC1,.

The title compounds were prepared via two efficient routes. The first sequence utilized a diastereospecific triflate alkylation in the key bond forming step while the second method relied on a novel intramolecular Mitsunobu reaction to set the required stereochemistry. Many pharmaceutical agents co
