## Abstract Azomethine ylides generated from 5‐(alkoxycarbonylmethyl)phenanthridinium cations were studied in 1,3‐dipolar cycloadditions with dimethyl maleate and dimethyl fumarate as dipolarophiles. The cycloadducts with the pyrrolidino[1,2‐f]phenanthridine skeleton easily underwent dehydrogenatio

1,3-Dipolar cycloaddition of D-glucose-derived azomethine ylides for the synthesis of chiral pyrrolidines accompanied an unexpected 1,2-elimination in the furanose moiety of the products. The C3 0 alkoxy/ hydroxy group of the furanose moiety was invariably eliminated under the reaction conditions. A

Methods are described of synthesizing various 3-carboxy-4-vinyl pyrrolidines, versatile building blocks for our drug discovery efforts. The 1,3-dipolar cycloaddition between activated olefins and nonstabilized azomethine ylide is a known method for synthesizing pyrrolidines in a stereospecific manne
