摘要
An efficient synthetic route for novel 2H-1,4-benzoxazin-3(4H)-ones via smiles rearrangement is developed. Reaction of primary amine and chloroacetyl chloride gave 2-chloroacetamide, which reacted with 2-chlorophenol, followed by Smiles rearrangement to obtain a series of new 2H-1,4-benzoxazin-3(4H)-ones (yield 45-90 %).
