Michael addition of heterocyclic amines (6), (10), (13) and (17) to nitro-olefin (3) followed by reduction/cyclization of the nitro group of the adduct provides a convenient synthesis of the bicyclic pyrazinones (8), (12), (16), (19) and (20) which are found in several natural products.
将杂环胺(6),(10),(13)和(17)迈克尔加成到硝基烯烃(3)上,然后将加合物的硝基还原/环化,可以方便地合成双环吡嗪酮(8) ,(12),(16),(19)和(20),它们存在于几种天然产物中。
