, p. 224 - 228 (2007/10/02)
A method for synthesis of highly substituted 2(1H)-pyridones is reported.Vinyl isocyanates, prepared from the corresponding α,β-unsaturated carboxylic acids, undergo cyclization with various enamines to furnish six-membered heterocycles.The methodology is exemplified by numerous examples.Application of this strategy is further illustrated by the synthesis of several aza steroid analogues.
