摘要：
An improved regioselective synthesis of naphth[1,2-b]oxepin-5-one 1 and naphth[2, 1-b]oxepin-5-one 2 has been described. The key step is one-step regioselective synthesis of 4-naphthoxybutanoic acids 3 and 4, formed from the corresponding naphthols, and their cyclisation to naphthoxepinones 1 and 2.
