SYNTHESIS AND REACTIONS OF CHROMAN-2-OLS AND THEIR BENZO ANALOGS WITH N-NUCLEOPHILES

Abstract
By the action of acetic acid on 2-morpholinochromanes, a series of chroman-2-ols were obtained in which the hydroxyl group is easily substituted by a primary or secondary amine or benzyl carbamate fragments. In the case of hydrazines and hydrazides of carboxylic acids, the corresponding hydrazones are isolated.
