Intramolecular carbon-hydrogen insertion of metal carbenes generated by catalytic diazo decomposition of diazocarbonyl compounds is a facile methodology for carbon-carbon bond formation.1-3 Although there are notable exceptions,& five- membered-ring formation is preferred,7J and regioselectivity is generally subject to defined electronic effects.9JO Enantiocontrol has recently been achieved with selected
通过重氮羰基化合物的催化重氮分解产生的金属卡宾的分子内碳氢插入是形成碳碳键的简便方法。 1-3 尽管有明显的例外,但优选五元环形成,7J 和区域选择性是通常受确定的电子效应影响。9JO 最近通过使用手性或同手性二铑 (I1) 羧酰胺、11J2 或羧酸盐、~~J~ 但即使使用四[甲基] 二铑 (I1)
