Diaryloxy methano phenanthrenes: a new class of antituberculosis agents
摘要:
A new series of diaryloxy methano phenanthrenes were prepared through tertiary-aminoalkylations of [(methoxy-phenyl)-phenanthren-9-yl-methyl]-phenols obtained from Friedel-Crafts alkylations on (methoxy-phenyl)-phenanthren-9-yl-methanols. These series of compounds were evaluated against Mycobacterium tuberculosis H37Rv and showed the desired activity in the range of 6.25 mug/mL in vitro. One of the compound 12j protects the mice from the challenge of M. tuberculosis in vivo, as 30% of the mice were survived at treatment of 50mg/kg body weight. (C) 2004 Elsevier Ltd.

The transition-metal-free synthesis of unsymmetrical and highly functionalized triarylmethanes through arylation of the situ generated o-QMs from diarylmethyl p-tolyl sulfones with aryl zinc reagents is described. Alkyl zinc reagents are also well tolerated in this reaction. Additionally, the straightforward synthesis of the analogue of the antituberculosis agent A and the key precursor of the anti-breast-cancer
