A highlyregio- and stereoselective hydration of 1,2-allenylicsulfoxides in which proton served as the electrophile was reported. Through the X-ray diffraction study, it was concluded that the reaction may proceed via a 5-membered cyclic intermediate following by attack of the −OH at the sulfur atom.

A highlyregio- and stereoselective oxidative hydroacetoxylation of 1,2-allenylicsulfoxides 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
