Method for making 5-membered ring compounds containing N, 0 or S atoms by reacting certain (thio)cyanate or cyanamide salts with compounds having NH2, OH or SH functionality vicinal to an-NH2 group, in the presence of an acid except where said cyanate is an ammonium salt.
制造含有 N、0 或 S 原子的五元环化合物的方法,在酸的存在下,通过使某些(硫代)氰酸酯或氰酰胺盐与具有 NH2、OH 或 SH 官能的化合物在 NH2 基团附近发生反应,但所述氰酸酯为铵盐的情况除外。
