  Green, efficient and practical Michael addition of arylamines to α,β-unsaturated ketones

  摘要：

  The aza-Michael addition of aromatic amines to alpha,beta-unsaturated ketones was carried out effectively at room temperature in good to excellent yields without any catalyst or solvent. It was significant that part of adducts could be collected in almost quantitative yield without column chromatography. This procedure offered a green, efficient, and practical approach for the synthesis of beta-amino ketones. (C) 2011 Elsevier Ltd. All rights reserved.

  (LMCT) process. These reactions exhibit remarkably broad substrate scope (>150 examples in total), and most importantly, all of these three reactions show unconventional regioselectivity, with the occurrence of C(sp3)–H borylation, thiolation, and sulfinylation preferentially at the distal methyl position. The procedures are operationally simple and readily scalable and provide access to high-value products

  催化 C(sp 3 )–H 功能化为构建有机分子提供了巨大机会，促进了复杂药物化合物的衍生化。在此框架内，直接氢原子转移 (HAT) 光催化成为实现这一目标的一种有吸引力的方法。然而，这些方案中使用的可行底物是有限的，并且位点选择性显示出对活化和热力学有利的 C(sp 3 )–H 键的偏好。在此，我们描述了无向铁催化 C(sp 3)–H 硼酸化、硫醇化和亚磺酰化反应由光诱导配体到金属电荷转移 (LMCT) 过程实现。这些反应表现出非常广泛的底物范围（总共 > 150 个例子），最重要的是，所有这三个反应都表现出非常规的区域选择性，C(sp 3 )–H 硼酸化、硫醇化和亚磺酰化优先发生在远端甲基位置。这些程序操作简单，易于扩展，一步即可从简单的碳氢化合物中获取高价值产品。机理研究和对照实验表明，所提供的位点选择性不仅与 HAT 物种相关，而且在很大程度上受到硼基和砜基自由基受体的使用的影响。
