  Potential Photoaffinity Labels for Tubulin. Synthesis and Evaluation of Diazocyclohexadienone and Azide Analogs of Colchicine, Combretastatin, and 3,4,5-Trimethoxybiphenyl

  摘要：

  Analogs of tubulin assembly inhibitors such as colchicine, combretastatin, and 3,4,5-trimethoxybiphenyl which incorporate a 6-diazo-2,4-cyclohexadienone (o-quinone diazide) ring have been synthesized and characterized. The compounds synthesized include 6-diazo-4-(2',3',4'-trimethoxyphenyl)cyclohexa-2,4-dien-1-one and its 3-methyl and 3-ethyl analogs (1a-c), 6-diazo-3-(2,3,4-trimethoxyphenyl)-2,4-cyclohexadien-1-one and its 4-methyl and 4-ethyl derivatives (2a-c), 4-[Z-2-(3',4',5'-trimethoxyphenyl)ethenyl]-6-diazocyclohexa-2,4-dienone (3), 3-[Z-2-(3',4',5'-trimethoxyphenyl)ethenyl]-6-diazocyclohexa-2,4-dien-1-one (4), the corresponding dihydro derivatives (5, 6) and two isomeric diazocyclohexadienones derived from N-acetylcolchinol (7, 8). Compounds in which the cyclohexadienone oxygen is approximately isostructural with carbonyl or hydroxy functions of the parent compounds exhibit good activity in the tubulin assembly inhibition assay. 2'-Alkyl-4'azido-3,4,5-trimethoxy-1,1'-biphenyls also show good activity as tubulin assembly inhibitors.

  A generalized protocol for the reductive carbonylation of (hetero) aryl halides and triflates under CO gas‐free conditions using Pd/Co2(CO)8 and triethylsilane has been developed. The mild reaction conditions, enhanced safety, and wide substrate scope highlight its importance in routine organic synthesis.

  protecting group for a phenol is conveniently unmasked under the conditions of the SNAr reaction with an activated aryl halide, producing diarylether products directly. The method is advantageous when the preparation of a phenol substrate requires O-protection, since the selection of the robust methanesulfonate as a latent phenol obviates a deprotection step prior to the SNAr reaction.
