Asymmetric total synthesis of (+)-sphaerodiol (2) has been achieved. A key step is an intramolecular [2 + 2] cycloaddition of alkyl(phenylthio)ketene for rapid assembly of the decalin ring.
Sulfur-Assisted Ring Expansion of the Potassium Salts of 1-Vinylcyclobutanols. A Versatile Synthesis of Cyclohexanones
Cohen, Theodore,Yu, Lin-Chen,Daniewski, Wlodzimierz M.
, p. 4596 - 4600 (2007/10/02)
Readily available 2-(phenylthio)-1-vinylcyclobutanols undergo a facile potassium hydride induced ring expansion to 4-(phenylthio)cyclohexanones.The sulfur substituent plays a key role.Evidence for a fragmentation to an enone-anion intermediate is discusse
