    微波辐射辅助手性助剂介导的钯-羰基亚胺钯的不对称还原
    摘要:
    通过原位还原由亚胺2和8-苯基薄荷基的氯甲酸酯作为手性助剂生成的N-酰基亚胺离子中间体,实现了另一种在β-咔啉部分中引入手性的合成方法。该方法采用微波辅助辐射,并使用PdCl 2 / Et 3 SiH协议作为温和的还原剂,与常规的热反应相比,该方法将反应时间缩短至数分钟。还原产生的R-胺的非对映选择性(4-12:1),与从Noyori不对称氢化催化剂获得的产物相比,在手性辅助去除和光谱数据后将其分配。

    Enantioselective total synthesis of (S)-(−)-quinolactacin B
    摘要:
    The enantioselective total synthesis of (-)-quinolactacin B (-)-1 was performed in seven steps and 33% overall yield from tryptamine. The synthesis features the use of ruthenium catalytic asymmetric hydrogen reaction to introduce the chirality in dihydro-beta-carboline 2. Based on Noyori's work, the hydrogenation using the (R,R)-TsDPEN-Ru complex produces dihydro-beta-carbolines possessing the (S) absolute configuration, the corrected asymmetric center of the natural product. The synthetic quinolactacin B displayed optical rotations that was in accordance with that of the natural product, thereby supporting the (S) configuration for natural quinolactacin B. The final product's stereochemical assignment is in agreement with that proposed by Nakagawa and co-workers. (C) 2008 Elsevier Ltd. All rights reserved.
