“…formation of the monoacetate and it is unlikely that the cyclopropanediol ( 19) is a precursor, since we have shown subsequently that acidolysis of the analogous bicyclic diol (20) gave none of the corresponding cyclohexenone. The bicyclic diol derivative (21) was synthesised by methylene (carbene) addition to 1,2-bis(trimet hylsi1oxy)cyclopentene; 7316 reaction with acetyl chloride gave the corresponding diacetate (22).…”
