资源简介：
The diastereo- and
enantioselective dearomative formal [3 + 2]
cycloaddition of 2-nitrobenzofurans and α-aryl-α-isocyanoacetate
esters provides tricyclic compounds bearing the 3a,8b-dihydro-1H-benzofuro[2,3-c]pyrrole framework with three consecutive stereogenic centers.
The reaction was enabled by a cupreine-ether organocatalyst. The reaction
products were obtained with almost full diastereoselectivity and with
excellent enantiomeric excesses for a number of substituted 2-nitrobenzofurans
and isocyanoacetates.
