N-substituted tetronamides as ambident nucleophilic building blocks for the synthesis of new 4-aza-2,3-didehydropodophyllotoxins

Madec, David,Mingoia, Francesco,Prestat, Guillaume,Poli, Giovanni

scheme or table, p. 1475 - 1478 (2009/04/07)

Aza-analogues of podophyllotoxin were synthesized in two steps from N-substituted tetronamides. The acid-mediated benzhydrylation of N-substituted tetronamides with a suitably func-tionalized benzhydrol quantitatively afforded the cyclization precursors.
