On the utility of α-heteroatom substituted orthoesters in the Johnson Claisen rearrangement

Article abstract of DOI:10.1016/S0040-4039(00)73290-4

α-Heteroatom substituted orthoesters were prepared and found to undergo the Johnson Claisen rearrangement with a variety of allylic alcohols giving γ,δ-unsaturated α-heteroatom substituted esters in fair to excellent yields. The diastereoselectivity of the process was examined.
