摘要

通过[3 + 3]环/开环级联反应，建立了n-杂环卡宾催化的喹啉-2- 1的不对称c4功能化反应。该方法以2-溴烯醛和3-羟基喹啉-2(1H)- 1为原料，在温和条件下，以中高收率合成了富集对映体的喹啉衍生物。

Asymmetric [3 + 3] annulation of 3-hydroxyquinolin-2-ones via NHC organocatalysis†

An efficient N-heterocyclic carbene (NHC)-catalyzed asymmetric C4-functionalization of quinolin-2-ones through a [3 + 3] annulation/ring-opening cascade reaction has been developed. This method employs 2-bromoenals and 3-hydroxyquinolin-2(1H)-ones to construct enantioenriched quinoline derivatives in moderate to good yields and with excellent enantioselectivity under mild conditions.
