An N-heterocycliccarbene (NHC) catalyzedasymmetric [3+3] annulation of α-bromoenals with 5-aminopyrazoles is described. Using the established methodology, a structurally diverse set of high value dihydropyrazolo[3,4-b]pyridine-6-ones were efficiently constructed in high yields (up to 99%) with excellent enantioselectivities (up to >99%). The easily available starting materials, broad substrate scope
描述了N-杂环卡宾 (NHC) 催化的α-溴烯醛与 5-氨基吡唑的不对称 [3+3] 环化反应。使用已建立的方法,以高产率(高达 99%)和出色的对映选择性(高达 >99%)有效地构建了一组结构多样的高价值二氢吡唑并[3,4- b ]吡啶-6-酮。易于获得的起始材料、广泛的底物范围、温和的反应条件、优异的产率和对映选择性使该策略对于吡唑并稠合吡啶酮衍生物的不对称构建具有吸引力。
