An organocatalytic enantioselective intermolecular oxidative dehydrogenative α-alkylation of aldehydes via benzylic C–H bond activation has been developed. The asymmetric reaction is smoothly fulfilled by using simple and green molecular oxygen as the oxidant. Two hydrogen dissociations make this transformation more environmentally benign because of high atom efficiency.
通过苄基CH键的活化,开发了醛的有机催化对映选择性分子间氧化脱氢α-烷基。通过使用简单的绿色分子氧作为氧化剂,可以平稳地完成不对称反应。由于高的原子效率,两个氢离解使这种转变在环境上更加无害。
