描述了一种在深度共晶溶剂(DES)中使用铜催化的方法从三芳基双变异蛋白,Na 2 S 2 O 5和硝基化合物开始可持续合成磺酰胺的方法。因此,将三芳基双突变蛋白用作掺入SO 2的试剂变成有机图案。通过用水沉淀,可以很容易地从粗反应混合物中除去作为副产物形成的铋盐,同时在整个过程中可以避免使用挥发性有机化合物(VOC)作为溶剂。用作溶剂的低共熔混合物已得到充分表征,初步结果证明其毒性低。设计的DES还可以进行新颖的多组分反应,从而节省时间并减少纯化步骤,能源和成本。

substituent could be used to predictably modulate the reactivity of the resulting CC-1065/duocarmycin alkylation subunit analogue is detailed and its extension to a unique series of N-alkenyl derivatives is reported. The N-aryl derivatives were found to be exceptionally stable and to exhibit well-defined relationshipsbetweenstructure (X-ray), reactivity, and cytotoxic potency. When combined with the results

modulate the reactivity of the resulting CC-1065/duocarmycin alkylation subunit analogue (rho = 0.17). The derivatives were found to be exceptionally stable and to exhibit a well-defined relationshipbetweenreactivity and cytotoxic potency. When combined with the results of an extensive series of N-acyl CBI analogues and derivatives assembled over the past 15 years, the studies define a fundamental parabolic

synthesis of tertiary bismuth(III) complexes containing amino or pyridyl functional groups has been investigated. An improved synthesis for Bi[p-C6H4(NMe2)]3 (1) has been achieved. Two new complexes, Bi[p-C6H4CH2(NPri2)]3 (2) and Bi[p-C6H4CH2N(2-Py)2]3 (3), have been obtained. The bismuth(V) derivatives of compounds 1 and 3 have been synthesized via chlorine oxidation of 1 and 3 and the subsequent substitution
