(Figure Presented) Improving the structural scope: A catalytic asymmetric 1,3-dipolar cycloaddition involving α-iminonitriles as azomethine precursors has been developed. In the presence of AgOAc/ Taniaphos as the catalyst system the reaction of α-iminonitriles with dimethyl fumarate and N-methyl maleimide affords 2-cyanopyrrolidines with good endo selectivity and enantioselectivity (68-≥99% ee; see scheme).

N-(Cyanomethyl)- and N-(α-cyanobenzyl)imines derived from a variety of aldehydes and ketones can tautomerize into N-protonated azomethine ylides which undergo cycloadditions with olefinic dipolarophiles.These cycloadditions are often accompanied by the el
