  Synthesis and biological activity of 1,4:3,6-dianhydro-2,5-diazido-2,5-dideoxyhexitols

  摘要：

  Reaction of 1,4:3,6-dianhydro-2,5-di-O-mesyl- and -tosyl-D-mannitol with sodium azide afforded the 2,5-diazido-L-iditol derivative. The analogous D-glucitol isomer was obtained in a similar reaction starting from the corresponding D-glucitol derivatives, and showed significant, hypnotic activity in animals. For establishing the structure-activity relationship, 1,4:3,6-dianhydro-2,5-diazido-2,5-dideoxy-L-mannitol (19), as well as its antipode 27 [1,4:3,6-dianhydro-2,5-diazido-2,5-dideoxy-D-mannitol] was synthesized, starting from D-mannitol. Compound 19 was as effective as Doriden (3-ethyl-3-phenylglutarimide), a hypnotic drug. The antipode 27 and the bioisosteric 1(4),3(6)-dithio derivative were inactive.

  The invention relates to new stereoisomeric 1,4;3,6-dianhydro-2,5-diazido-2,5-dideoxy-hexitols of the Formula I. These compounds can be prepared by (a) reacting a hexitol derivative of the general Formula II /wherein R is a mesyl or tosyl group/ in an aqueous or anhydrous organic solvent with an alkali metal azide or ammonium azide; or (b) mesylating or tosylating a compound of the Formula III and treating the mixed ester of the general Formula IV thus obtained /wherein R is as stated above/ with a base; or (c) subjecting a compound of the Formula III to debenzoylation and subsequently to partial esterification and treating the compound of the general Formula V thus obtained /wherein R is as stated above/ with a base. The new compounds of the Formula I possess valuable hypnotic properties and can be used in therapy. ##STR1##
