Michael addition of nitroparaffins to α,β-unsaturated sulfoxides is well effected in the presence of DBU. The nitro group in the adduct is replaced by hydrogen with Bu3SnH without influence to the sulfinyl function. The overall reations provide an efficient method for the conjugate addition of alkyl groups to α,β-unsaturated sulfoxides.
在DBU的存在下,将硝基链烷烃迈克尔加成到α,β-不饱和亚砜上是有效的。加合物中的硝基被Bu 3 SnH取代为氢,而不影响亚磺酰基的功能。整体反应为将烷基共轭加成到α,β-不饱和亚砜上提供了一种有效的方法。
