Trimethyl 3-(phenylseleno)orthopropionate may be utilized as a synthon for the preparation of either 2-substituted acrylates or a-methylene-Y-butyrolactones via Claisen ortho ester rearrangement with allylic alcohols followed by oxidative-elimination of PhSeOH. The 2-substituted acrylate moiety is p
Polystyrene-diethylsilane resin (PS-DES) was treated with triflic acid to form a highly reactive polymer silyl triflate. The silyl triflate reacted with enolizable allylic esters in the presence of Et3N to afford resin-bound silyl ketene acetals, which undergo Ireland-Claisen rearrangement at elevat
