摘要
(Chemical Equation Presented) As radical chain cascade precursors, N-acylcyanamides give rise to amide-iminyl radicals which, when appropriately substituted, can finally yield pyrroloquinazolines. The versatility of these new radical acceptors is illustrated by the formation of N-heterocycles with wide structural variation and by the total synthesis of luotonin A. © 2007 Wiley-VCH Verlag GmbH & Co.
