Title: PROCESS FOR PREPARING OXADIAZACYCLO COMPOUND AND USE THEREOF
Abstract:
Provided are a process for preparing an oxadiazacyclo compound and the use thereof. An N-alkoxycarbonyl hydrazine is cyclized with a disubstituted ether under the action of an alkali to give an N-alkoxycarbonyl oxadiazacyclo compound, and the latter and an alkali are subjected to a deprotection reaction to give the oxadiazacyclo compound. The process uses a new N-protection strategy, such that not only is the use of an expensive protective reagent avoided, but the reaction yield is also improved. Moreover, the preparation process further has the following advantages: same contains less of the three wastes and is simple to operate, uses equipment which will not easily corrode, etc., and is favorable for industrial production.
