摘要:

AbstractWittig reagents (1a–c) react with N‐(phenylsulfonyl)‐1,4‐benzoquinone monoimine2ato give adducts3a,4a, and4b. On the other hand, the reactions of2bwith the same ylides (1a–c) yield the new products3b,6a, and6b, respectively. Mechanisms accounting for the formation of the new products are discussed and the probable structures of the products are presented, based on compatible analytical and spec
