Stereoselective synthesis of functional derivatives of 2-(2-carboxyethyl) pyrrolidine-2-carboxylic acid

, p. 412 - 422 (2007/10/03)
Azomethine ylides generated from dimethyl 2-(arylmethylideneamino) pentanedioates by the action of AgOAc and Et3N reacted with dipolarophiles in regio- and stereoselective fashion to form 5-aryl-2-(2-carboxyethyl)pyrrolidine-2-carboxylic acid derivatives. 1,3-Dipolar cycloaddition of divinyl sulfone to the azomethine ylide generated from the Schiff base derived from methyl (S)-2-phthalimido-4-oxobutanoate and dimethyl glutamate gave chiral simplified kaitocephalin analogs.

5-Endo-Trig Cyclisation and 1,3-Anionic Cycloaddition in Arylimine Derivatives of α-Amino Acid Esters
Grigg, Ronald,Kemp, James,Malone, John,Tangthongkum, Anant
, p. 648 - 650 (2007/10/02)
Michael adducts of imines of α-amino acid esters are converted into a mixture of two stereoisomeric pyrrolidines by benzyltrimethylammonium methoxide (BTAM) apparently by a 5-endo-trig cyclisation.
