Compounds having .alpha. adrenergic activity and useful for the treatment of glaucoma, renal and gastrointestinal disorders and vasoconstictors have the formula ##STR1## where R.sub.1 is independently H, or lower alkyl or 1 to 6 carbons; R.sub.2 is independently H, or lower alkyl of 1 to 6 carbons or the two R.sub.2 symbols jointly represent a carbonyl oxygen; R.sub.3 is H, lower alkyl of one to 6 carbons, O, OH and OR.sub.7 where R.sub.7 is lower alkyl of 1 to 6 carbons, or R.sub.3 is COH or COR.sub.8 where R.sub.8 is lower alkyl of 1 to 6 carbons; R.sub.4 and R.sub.5 independently is H, Br, Cl, or lower alkyl of 1 to 6 carbons, lower alkenyl or lower alkynyl with the proviso that when the R.sub.2 groups symbolize a carbonyl oxygen then R.sub.4 and R.sub.5 both cannot be hydrogen; R.sub.6 is hydrogen, Br, Cl, or lower alkyl of 1 to 6 carbons, lower alkenyl or lower alkynyl, and the R.sub.5 and the (2-imidazoline-2-yl)amino substituents are connected mutually exclusively to the 6 and 7 positions of the 1,4-benzoxazine nucleus.
具有α肾上腺素活性并用于治疗青光眼、肾脏和胃肠道疾病以及血管收缩剂的化合物具有以下结构式:其中R.sub.1独立地是H,或较低碳原子数的烷基或1至6个碳原子;R.sub.2独立地是H,或1至6个碳原子的较低烷基,或两个R.sub.2符号共同代表一个羰基氧;R.sub.3是H,1至6个碳原子的较低烷基,O,OH和OR.sub.7,其中R.sub.7是1至6个碳原子的较低烷基,或R.sub.3是COH或COR.sub.8,其中R.sub.8是1至6个碳原子的较低烷基;R.sub.4和R.sub.5独立地是H,Br,Cl,或1至6个碳原子的较低烷基,较低烯基或较低炔基,但当R.sub.2基团代表一个羰基氧时,R.sub.4和R.sub.5都不能是氢;R.sub.6是氢,Br,Cl,或1至6个碳原子的较低烷基,较低烯基或较低炔基,而R.sub.5和(2-咪唑啉-2-基)氨基取代物相互独占地连接到1,4-苯并噁唑啉核的6和7位置。
