Huang, Pei-Qiang,Fan, Ting
, p. 6369 - 6374 (2017/10/24)
Although the aldol condensation is a well-known reaction, the aza-type aldol condensation, namely, the intramolecular condensation of common keto lactams leading to bicyclic vinylogous lactams, is a highly demanding transformation, with potential applicat
USE OF INTRAMOLECULAR AZA-WITTIG REACTION FOR THE ACCESS TO 2-CYCLOPROPYL CYCLIC IMINES WHICH ARE KEY INTERMEDIATES IN THE SYNTHESIS OF BICYCLIC ALCALOIDS
Vaultier, M.,Lambert, P. H.,Carrie, R.
, p. 449 - 456 (2007/10/02)
A simple access to functionalized 2-cyclopropyl cyclic imines via an intramolecular aza-Wittig reaction is described.The thermal rearrangement of these compounds in the presence of trace amounts of ammonium chloride leads to bicyclic (x=3,4,5) vinylogous urethanes and amides in good yields.
