Enacylamines

The photocyclization of enamides has been the subject of detailed study and provides a valuable approach to the synthesis of alkaloids. A comprehensive review has been published.31 A variety of reaction types has been reported. The N-benzoylenamine 33, for example, is converted on irradiation to the trans-lactam 34 by a process involving conrotatory photocyclization followed by a thermally allowed [l,5]-suprafacial hydrogen migration.32 The influence of substituents on this transformation has been studied.33 The enacylamine 35 undergoes an analogous cyclization to give a mixture of cis- and trans-lactams 36, the ratio of which is solvent... [Pg.245]
