The 4-oxoalkyl- and 4-iminoalkyl-5-azidothiazoles undergo a ring transformation with nitrogen loss at relatively low temperatures to afford 4-cyanooxazoles and 4-cyanoimidazoles, respectively. The mechanism, which is thought to involve a ring opening-ring closure process, is discussed.
在相对较低的温度下,4-氧代烷基-和4-亚氨基烷基-5-叠氮基噻唑经历环转移和氮损失,分别得到4-氰基恶唑和4-氰基咪唑。讨论了该机制,该机制被认为涉及开环-闭环过程。
