The synthesis of the pentacyclic skeleton of Et-743 and the construction of the five chiral centers thereof.1. The core pentacyclic skeleton of phthalascidin was constructed with L-dopa as the starting material via thirteen steps. First, two basic synthons, the C-1 functionalized tetrahydroisoquinoline compounds 8 and N-protected Z-dopa derivative 9, were prepared from L-dopa. They were coupled via amide bond to form the dipeptide compounds 10, which were the first key intermediates. Then the primary hydroxyl groups were transformed into the corresponding amino aldehydes 11 via Swern oxidation. Followed by the intramolecular Pictet-Spengler cyclization, the pentacyclic compounds 12 were synthesized.
五环骨架的构建及五个正确手性中心的确立:1.1我们以L-多巴为起始原料,经过多步官能团保护和转化合成了基本结构单元8然后和苯丙氨酸衍生物9,通过缩合反应生成酰胺中间体10,经Swern氧化得到醛化合物11,然后再次利用分子内改良的Pictet-Spengler反应一步构建c,d两环,得到五环骨架化合物12,最后,实现了21-位羰基向氰基的转化,得到了C-1位官能化的化合物14,化合物14不但具有和Et-743一致的五环骨架,而且分子中五个手性中心立体构型也与其完全相同:其中,3,位和13,位的手性中心由原料L-多巴带入,而1,位,11,位和21,位手性中心则通过不对称诱导而确立。
