Penems: synthesis and antibacterial activity of 2-(1-azolyl) derivatives.
thesis by Woodward1},many research groups have prepared variously substituted penems, including derivatives bearing hetero-substituents at C-2. Whereas the vast majority of these have been sulfur derivatives2~6), analogous to the naturally occurring thienamycin and a few 2oxy-substituted penems have been synthesized70 , no nitrogen derivatives have yetf been described. In continuation of our st...
متن کاملSYNTHESIS OF 1, l1-DIHYDROXY-2,2'- (THIODIMETHYLENE) BIS-9(1 OH)-ANTHRONE
An efficient synthesis of the 1,l'-dihydroxy-2,2'-(thiodimethy1ene)bis-9(10H)- anthrone (5) is described. Reaction of 1 -methoxy-2-(bromomethy1)-9,lOanthraquinone (1) with excess sodium sulfide in ethanol, demethylation to the corresponding hydroxy and subsequent selective reduction produced the title compound in high yield.
متن کاملCoordination Chemistry of Tris(azolyl)phosphines
An overview is given of the chemistry of tris(azolyl)phosphines with focus on their preparation and application in coordinationand organometallic chemistry and catalysis. These systems share with the more abundant tris(pyrazolyl)borates and -methanes the ability to function as tridentate nitrogen ligands with hemilabile character, but the additional phosphine donor site grants them bifunctional...
متن کامل" BISCYCLISATION" SYNTHESIS OF 1,8-DIHYDROXY-9, 1 0- ANTHRAQUINONE (1,8-DHA)
The synthetic route in this work is based on the classical Friedel-Crafts strategy, and began with 1,4-dimethoxybenzene (I), followed by alkylation and selective demethylation of 2-methoxy function in 0x0-acid (3). The orthoformylation to synthesize aldehyde (6) was based on the Reimer-Tieman reaction. Chain extension of this aldehyde required methylation of the hydroxyl group and condensat...
