The 1-cyano-1-thiophenylcyclopentone derivative 1, obtained from (R,R)-(+)-tartaric acid, has been converted into a number of derivatives including the important trans-(3S,4S)-dibenzyloxycyclopentanone 2 in 45% overall yield.
An efficient synthesis of both enantiomers of trans-3,4-bis(benzyloxy)cyclopentanone 4, potential precursors to the five-membered (A)-ring of the neocarzinostatin chromophore, was accomplished from diethyl tartrate in 7 steps.
