Stereocontrolled intramolecular michael-aldol reaction mediated with bu2botf and (tms)2nh
摘要:
Treatment of keto-esters 1-5 with Bu(2)BOTf and (TMS)(2)NH caused a tandem Michael-aldol reaction to give polycyclic cyclobutanes 6-10 with high stereoselection. It was proved that the reaction was accelerated by the addition of Bu(4)NI.
