Article Synopsis
- The study describes a multi-step synthesis of 2-diazo-3-oxo-4-phthalimidocarboxylic esters from methionine, S-benzylcysteine, and S-allylcysteine.
- Upon rhodium-catalyzed dediazoniation, two types of carbenoid reactions occur, leading to the formation of different ylides, where S-methyl and S-benzyl ylides could be isolated while S-allyl ylide underwent rearrangement.
- The short-lived carbonyl ylides produced from methionine and S-benzylcysteine form dimers and can react with dipolarophiles, while the S-allyl derivative leads to a
