A new synthetic access to furo[3,2-f]chromene analogues of an antimycobacterial
摘要:
From the structure of 3,3-dimethyl-3H-benzofuro[3,2-f][1]-benzopyran, a selective in vitro inhibitor of mycobacterial growth, we have undertaken a structure-activity relationship investigation. We wish to report here our results on the use of [2+3] cycloadditions between 2-formylbenzoquinone and various enol derivatives to give various 4-formyl-5-hydroxy benzofurans. In the next step, an ytterbium triflate-catalysed reaction with 2-methylpropene allowed the preparation of various original furo[3,2-f]chromenes derivatives. Their biological evaluation on the growth of Mycobacterium smegmatis as well as Mycobacterium tuberculosis pointed out that some analogues were four times more active than the initial hit.

and even more simple, we prepared the ((6-hydroxy-2,2,7,8-tetramethylchroman-5-yl)methyl)triphenylphosphonium salt via a selective bromination of 2,2,5,7,8-pentamethylchroman-6-ol. From this salt, a two stage Wittig reaction with an array of activated acids allowed the quick preparation of many analogues. The biological evaluation of the effect of these compounds on the growth of Mycobacterium bovis
我们先前报道了4-(7,7-二甲基-7 H-呋喃[3,2 - f ] chromen-2-yl)吡啶的合成和抗分枝杆菌活性。从这个结果,我们试图设计对相关结构的简单合成途径,以允许制备各种类似物。研究了两种方法。由3-(2-溴-7,7-二甲基-8,9-二氢-7 H-呋喃[3,2 - f ]铬-1-基)丙基乙酸酯,我们通过Suzuki-Miyaura制备2-芳基化的衍生物这种含溴化合物与各种芳基硼酸酯之间的反应。此外,甚至更简单,我们制备的((6-羟基- 2,2,7,8四甲基-5-基)甲基)三苯基鏻盐通过2,2,5,7,8-五甲基苯并吡喃-6-醇的选择性溴化反应。从该盐开始,与一系列活化酸进行两步维蒂希反应,可以快速制备许多类似物。这些化合物对牛分枝杆菌和结核分枝杆菌生长的影响的生物学评估指出,所制得的化合物之一的抗分枝杆菌特性提高了四倍。然而,在相同浓度范围内,许多抑制结核分枝杆菌生长的类似物在0
