γ-Oxygenation of α,β-Unsaturated Esters by Vinylogous O-Nitroso Mukaiyama Aldol Reaction
摘要:
A practical procedure has been developed for gamma-oxygenation of alpha,beta-unsaturated esters by a vinylogous O-nitroso Mukaiyama aldol reaction followed by a one-pot N-O bond heterolysis of the in situ generated gamma-aminoxy-alpha,beta-unsaturated esters.
