## Abstract The title compound 9 was prepared by the route outlined in Scheme I. [^14^C]Thiourea (1) was condensed with ethyl 4‐bromo‐3‐oxo‐2‐methoxyiminoacetate (2), providing ethyl 2‐(2‐amino‐4‐[2‐^14^C]thiazolyl)‐2‐methoxyiminoacetate (3), as the pure Z‐isomer. Saponification gave the amino acid

## Abstract 4‐(Dicyanomethylene)‐3‐methyl‐1‐phenyl‐2‐pyrazoline‐5‐one (1) readily reacts with α‐amino acids and their esters by Michael addition and subsequent elimination of HCN to the adducts 2a–k. One of these, 2i (obtained from methyl glycinate), adds stereoselectively to __N__‐phenylmaleimide
