The invention relates to new derivatives of 3-oxo-2,3-dihydro-1,4-benzoxazine corresponding to the general formula ##SPC1## In which R.sub.1 is selected from the group consisting of the hydrogen atom and a lower alkyl group; R.sub.2, r.sub.3 and R.sub.4 which are identical or different, are selected from the group consisting of the hydrogen atom, a halogen atom, a nitro group, a lower alkyl group, a lower alkoxy group and R.sub.4 may be an allyl group; R.sub.5 is selected from the group consisting of the hydrogen atom and an acyl group, preferably acetyl. These derivatives can be used for therapeutic purposes, more especially as analgesics and anti-oedematous agents.
该发明涉及与一般式##SPC1##相对应的3-氧代-2,3-二氢-1,4-苯并噁嗪的新衍生物。其中,R.sub.1选自氢原子和较低的烷基;R.sub.2、r.sub.3和R.sub.4相同或不同,选自氢原子、卤素原子、硝基、较低的烷基、较低的烷氧基,R.sub.4可能是烯丙基;R.sub.5选自氢原子和酰基,最好是乙酰基。这些衍生物可用于治疗目的,尤其是作为镇痛剂和抗水肿剂。
