Traffic control: The hydroxy functional group directs the α‐functionalization of tertiary amines, synthesizing 1,3‐oxazines by CO bond formation. Reaction occurs with both benzylic and non‐benzylic amines. In the case of naphthoxazine synthesis, 100 % diastereoselectivity was observed. A tentative two‐pathway mechanism is proposed for the reaction.
交通控制:羟基官能团指导叔胺的α-官能化,通过CO键的形成合成1,3-恶嗪。与苄基和非苄基胺都发生反应。在萘并恶嗪合成的情况下,观察到100%的非对映选择性。对于该反应,提出了一种暂定的两种途径的机制。
