exclusively the corresponding β-nitro alcohol adducts in excellent yields under very mild conditions. Design aspects of metal-free nitrogen-based catalysts and their influence on the yield in the Henry reaction are disclosed. C 1-Symmetric, N,N-1,2-disposed amine-imine type catalysts were found to be most efficient. C 1-N,N-1,2-Disposed 1,2,3,4-tetrahydro-1,1′-biisoquinoline selectively and efficiently catalyzed
摘要 公开了无金属氮基催化剂的设计方面及其对亨利反应中产率的影响。发现C 1-对称的,N,N -1,2布置的胺-亚胺型催化剂是最有效的。C 1 - N,N -1,2-取代的1,2,3,4-四氢-1,1'-二异喹啉选择性和有效地催化将硝基甲烷添加到α-酮酯和醛中,仅给出相应的β-硝基在非常温和的条件下,醇加合物的收率很高。 公开了无金属氮基催化剂的设计方面及其对亨利反应中产率的影响。发现C 1-对称的,N,N -1,2布置的胺-亚胺型催化剂是最有效的。C 1 - N,N -1,2-取代的1,2,3,4-四氢-1,1'-二异喹啉选择性和有效地催化将硝基甲烷添加到α-酮酯和醛中,仅给出相应的β-硝基在非常温和的条件下,醇加合物的收率很高。
