ANIONS LITHIENS DERIVES D'AZA-2 ALLYLPHOSPHONATES. SYNTHESE REGIO ET STEREOSPECIFIQUE DE NOUVELLES δ1-PYRROLINES
Dehnel, Andre,Lavielle, Gilbert
, p. 1315 - 1318 (1980)
Novel δ1-pyrrolins are obtained by the 1,3-cycloaddition of lithio-anions derived from 2-aza-allylphosphonates on actived double bonds; phosphite is then eliminated.
