, p. 439 - 454 (2007/10/03)
We have previously reported a new synthesis of amides from esters and amines under microwave irradiation, offering much higher yields than those achieved with conventional heating [1]. We have now extended these studies to the ring closure of neat iminoes
Generation of an N-Sodioazomethine Ylide and Its Cycloadditions with α,β-Unsaturated Esters
Kanemasa, Shuji,Yoshioka, Manabu,Tsuge, Otohiko
, p. 2196 - 2200 (2007/10/02)
Treatment of methyl 2-(benzylideneamino)propanoate with sodium hydride in THF generates an N-sodioazomethine ylide, which shows a very poor stereoselectivity in the cycloaddition with methyl acrylate.However, addition of such a base as triethylamine or t-
X=Y-ZH SYSTEMS AS POTENTIAL 1,3-DIPOLES. PART 15. AMINE GENERATED AZAALLYL ANIONS VERSUS METALLO-1,3-DIPOLES IN CYCLOADDITIONS OF α-AMINO ACID ESTERS. FACILE REGIO- AND STEREO-SPECIFIC FORMATION OF PYRROLIDINES.
Barr, Darrin A.,Grigg, Ronald,Gunaratne, H.Q. Nimal,Kemp, James,McMeekin, Peter,Sridharan, Visuvanathar

Kinetic studies of the deprotonation of arylidine imines of alanine and phenylglycine esters by tertiary amines and pyridine and cycloaddition of the resultant 4?-azaallyl anions to N-phenylmaleimide show the expected dependance on the p-substituent in th
