  Modular Synthesis of Lamellarins via Regioselective Assembly of 3,4,5-Differentially Arylated Pyrrole-2-carboxylates

  摘要：

  A modular synthesis of lamellarins via 3,4,5-differentially arylated pyrrole-2-carboxylate intermediates has been developed. The key reactions employed are Br-Li exchange-methoxycarbonylation of 2,5-dibromo-1-(tert-butoxycarbonyl)-1H-pyrrole (1) followed by palladium-catalyzed iterative Suzuki-Miyaura coupling of the pyrrole core. The 3,4,5-triarylpyrrole 4 thus synthesized was readily converted to 5,6-saturated lamellarin L (2) and 5,6-unsaturated lamellarin N (3) via lactonization followed by annulation of the pyrrole nitrogen and lateral aromatic ring at C5 using 2-bromoethyl phenyl sulfide or bromoacetaldehyde dimethyl acetal as two-carbon homologation agents. In principle, this strategy allows the production of diverse lamellarins in short steps with high yields using readily accessible arylboronic acids as aromatic modules.

  A modular synthesis of lamellarins has been developed. The key reactions in this synthesis are the assembly of 1,2-diarylated [1]benzopyrano[3,4-b]pyrrol-4(3H)-ones from a preexisting [1]benzopyrano[3,4-b]pyrrol4(3H)-one core and the appropriate arylboronic acids. The obtained 1,2-diarylated [1]benzopyrano[3,4-b]pyrrol-4(3H)-ones could be easily converted into the corresponding lamellarin derivatives

  已经开发了层状蛋白的模块化合成。该合成中的关键反应是由预先存在的[1]苯并吡喃[3,4-b]吡咯4( 3H)-一个核心和适当的芳基硼酸。得到的1,2-二芳基[1]苯并吡喃[3,4-b]pyrrol-4(3H)-ones可以通过吡咯氮和C2芳环之间的分子内环化很容易地转化为相应的层状结构衍生物。引言 层层素是一种多环吡咯生物碱，具有独特的 14-苯基-6H-[1]苯并吡喃[4́,3́:4,5]吡咯并[2,1-a]异喹啉-6-环系统。在极少数情况下（层状蛋白 O、P、Q 和 R），这些化合物具有简单的非稠合 3,4-diarylpyrrole-2-carboxylate 结构。自从第一次从海洋前支软体动物 Lamellaria sp. 中分离出层状蛋白 A-D。1985 年，从被囊类动物、海绵类和前枝类动物中分离出 50 多种层状蛋白。这些层状蛋白表现出广泛的有用生物活性：针对几种癌细胞系的有效抗增殖活性、多药耐药性
