    可切换的反应性:三氟甲基取代吡唑的位点选择性功能化
    摘要:
    现代有机金属方法能够将简单的杂环起始材料区域灵活地转化为异构体和同系物家族。取决于试剂的选择,1-甲基-5-(三氟甲基)吡唑主要或仅在杂环的4-位或在氮连接的Me基团上经历去质子化和随后的羧化。类似地,1-苯基-5-(三氟甲基)吡唑和3-甲基-1-苯基-5-(三氟甲基)吡唑在杂环4-位被二异丙基氨基锂选择性攻击,在4-位被丁基锂和Ph 环的正交位置。相比之下,1-甲基-3-(三氟甲基)吡唑的金属化仅发生在 5 位,无论是有机金属碱还是金属氨化物碱。如果将溴引入杂环或芳基中,则其他位点可进行功能化。戒指。4-溴-1-甲基-5-(三氟甲基)吡唑、4-溴-1-甲基-3-(三氟甲基)吡唑、4-溴-1-甲基-5-(三氟甲基)吡唑和1-(2-溴苯基)-5-(三氟甲基)吡唑。[在 SciFinder (R) 上]

  • Utility of Complementary Molecular Reactivity and Molecular Recognition (CMR/R) Technology and Polymer-Supported Reagents in the Solution-Phase Synthesis of Heterocyclic Carboxamides
    作者:John J. Parlow、Deborah A. Mischke、Scott S. Woodard
    DOI:10.1021/jo970571i
    日期:1997.8.1
    The use of our recently reported chemical library purification strategy in the development of a herbicidal lead, N-(3-benzoylphenyl)-3-(1,1-dimethylethyl)-1-methyl-1H-pyrazole-5-carboxamide (3), is described. The approach applying fundamental properties of complementary molecular reactivity and molecular recognition (CMR/R) as the basis for a general purification strategy was utilized. Polymeric reagents were used in the synthesis to generate reactive species involved in product formation, and complementary molecular reactivity/molecular recognition polymer 8 (CMR/R polymer 8) was used in the solution-phase syntheses of building blocks, primary libraries, and lead refinement libraries. An extension of the CMR/R methodology was applied, utilizing a sequestration enabling reagent (SER), transforming a reactant into an electrophilic species sequestrable by CMR/R polymer 8. This library purification strategy enabled rapid lead generation and lead refinement to afford herbicide 27o. The CMR/R solid-phase purification technique enabled a simple, general, and powerful protocol, eliminating the usual tedious and time-consuming methods required for solution-phase product purification. The result was the synthesis of hundreds of compounds, prepared in a relatively short time, leading to a compound with a 4-fold improvement in herbicidal activity over the initial lead.
