Abstract

NEW MATERIAL:A compound of formula I (R1 is H or hydrocarbon residue; one of R2 and R3 is electrically negative group and the other is H or hydrocarbon residue; X is methylene, carbonyl or thiocarbonyl; A may have a substitution group).
EXAMPLE: 3,4-Dihydro-2H-1,4-benzoxazine-2-acetic acid methyl ester.
USE: Medicines and their intermedates. It has analgesic, antiphlogistic, antidepressive and antispasmodic actions.
PROCESS: The objective compound of formula I is prepared by reacting a compound of formula II with a compound of formula III (X' is methylene or carbonyl; Y is halogen), and subjecting the resulting compound of formula IV to cyclization and if necessary, hydrolysis, reduction, sulfurization, introduction of hydrocarbon residue, etc.
