Chiral Guanidines in Michael Reactions,ioesters, amides, nitriles and nitro compounds) have been efficiently achieved by using chiral acyclic or cyclic guanidines as organocatalysts. They act not only as superbases but also through a hydrogen bond activation mode either of the nucleophile or of the electrophile. By this methodology, a se作者: febrile 時間: 2025-3-23 16:02
Chiral Bicyclic Guanidine, Bis-Guanidinium, Pentanidium and Related Organocatalysts,nown modes of interactions of these catalysts, such as Br?nsted base–Br?nsted acid and Br?nsted–Lewis acid bifunctional activations will be discussed in this account. Pentanidiums are ‘super-guanidines’ with extended conjugation, and their roles in catalysis and halogen bonding will also be elaborat作者: 褻瀆 時間: 2025-3-23 19:14 作者: Coma704 時間: 2025-3-24 00:46
