in the syntheses of 8 and 9 is a cobalt‐catalyzed [2+2+2] cycloaddition reaction that affords the 1,3‐disilaindane and 2‐oxa‐1,3‐disilaindane skeletons. Disila‐bexarotene and its analogues 8 and 9 were studied for their biological effects relative to all‐trans retinoic acid in cultured human pluripotent stem cells. The parent carbon compound bexarotene was included in some of these biological studies
临床使用的RXR选择性类维生素A激动剂贝沙罗汀的双倍Sila替代(C / Si交换)导致双硅贝沙罗汀,与基于母体碳化合物的药理学效力相似,如基于HeLa细胞的RXR分析所示。二硅贝沙罗丁烯中的SiCH 2 CH 2 Si基团与SiCH 2 Si或SiOSi部分的形式交换导致了二硅贝沙罗丁类似物8和9。所述硅化合物8和9在多步合成中被合成,从HCC开始(CH 3)2 SICH 2的Si(CH 3)2 CCH和HCC(CH3)2 SiOSi(CH 3)2 CCH,分别。合成8和9的关键步骤是钴催化的[2 + 2 + 2]环加成反应,该反应提供了1,3-二硅二氢化茚和2-oxa-1,3-二硅二氢化茚骨架。研究了Disila-bexarotene及其类似物8和9在培养的人多能干细胞中相对于全反式视黄酸的生物学效应。这些生物学研究中包括母体碳化合物贝沙罗汀。尽管含硅的贝沙罗汀类似物disil
