摘要:
Novel 1-(2-,3- or 4-hydroxylaminobenzensulfonyl-1a,2,6,6 a-tetrahydro-1H,4H-[1,3]-dioxepino[5,6-b]azirines with hypoglycemic activity are prepared by selective reduction of appropriate 1-(2-,3- or 4-nitrobenzenesulfonyl) derivatives.
摘要:
Starting from cis-2-butene-1,4-diol, via the 4,7-dihydro-1,3-dioxepin and trans-6-acylamino-5-chloro-1,3-dioxepans the novel tetrahydro-[1,3]-dioxepino[5,6-b]-azirines were synthesized, and therefrom the novel hypoglycaemically active N-sulfonyl-tetrahydro-[1,3]-dioxepino[5,6-b]azirines. The inventive compounds are valuable intermediates in the synthesis of other, biologically active substances.
摘要:
Novel O-substituted or O-unsubstituted 6-sulfonamido-1,3-dioxepane-5-ols having hypoglycemic activity are obtained from 6-amino-1,3-dioxepane-5-ol, tetrahydro-6H-[1,3]-dioxepino[5,6-d]oxazole, 5,6-epoxy-1,3-dioxepane or N-sulfonyl-tetrahydro-1H,4H-[1,3]-dioxepino[5,6-b]azirine as starting materials.
