Highly regio- and stereoselective oxidative hydroacetoxylation of 1,2-allenylic sulfoxides via a different mechanism.
A highly regio- and stereoselective oxidative hydroacetoxylation of 1,2-allenylic sulfoxides affording 1-sulfonyl-1-alken-3-yl acetates in moderate to good yields was developed. Through the X-ray diffraction study, it was observed that the reaction may proceed via a 5-membered cyclic intermediate and the (-)OAc attacks the chiral carbon atom, which is different from what was observed in our previous study.
