资源简介：
The first highly diastereoselective
and enantioselective catalytic
formal [4 + 3] cycloaddition of 1,1-cyclobutane diester with nitrone
has been developed. Sterically hindered chiral SaBOX/Cu(II) complex
promotes the reaction efficiently with a broad substrate scope, producing
a range of multifunctionalized optically active 1,2-oxazepanes with
excellent stereocontrol (up to >99/1 dr and 97% ee).
