One-pot SuzukiâMiyaura-type and Kumada-type cross-coupling reactions of 2,4-diiodo-buta-1-enes with arylboronic acids and alkyl/aryl magnesium bromides were carried out in the presence of accessibly simple catalysts under mild conditions. As a result, some 1,1,2-trisubstituted buta-1,3-dienes were obtained including the Tamoxifen-type, which have potential adjuvant therapy in women who have suffered from breast cancer and cyclooxygenase-2-type (COX-2-type) inhibitors, some of which have been proved to elicit efficient anti-inflammatory analgesic activities and less adverse gastrointestinal side effects and to be very useful in the prophylactic treatment of a wide variety of cancers and neurodegenerative disorders.
在温和条件下,使用易得的简单催化剂,进行了2,4-二
碘丁-1-烯与芳基
硼酸和烷基/芳基
溴化镁的单锅铃木-宫浦反应和熊田反应。因此,获得了一些1,1,2-三取代的丁-1,3-二烯,包括
他莫昔芬类物质,这些物质在经历过乳腺癌的女性中具有潜在的辅助治疗效果,以及环氧酶-2类(COX-2类)
抑制剂,其中一些已被证明具有有效的抗炎镇痛活性,并且不良的胃肠道副作用较少,且在多种癌症和神经退行性疾病的预防性治疗中非常有用。
