Substituted vinyl and ketene acetals undergo smooth oxygen-to-carbon rearrangement with a catalytic amount of TMSOTf to afford chain-extended ketones or esters, respectively. The developed procedure has been applied to the stereoselective synthesis of C-glycosides from the corresponding anomeric vinyl ethers.
取代的乙烯基和乙烯酮缩醛经过催化量的TMSOTf进行平稳的氧碳重排,分别得到扩链的酮或酯。已开发的方法已用于由相应的异头乙烯基醚立体选择性合成C-糖苷。
