An enantioconvergent synthesis of chiral cyclic allylboronates from racemic allylic bromides was achieved by using a guanidine-copper catalyst. The allylboronates were obtained with high γ/α regioselectivities (up to 99:1) and enantioselectivities (up to

Recent Advances in Chiral Guanidine Catalyzed Enantioselective Reactions.
Chemistry - An Asian Journal, 2019Chiral guanidines have been widely used as Brønsted base catalysts and phase transfer catalysts in enantioselective reactions. Due to their amendable structure and powerful catalytic ability, they have attracted much interest.

Metal-catalysed reactions enabled by guanidine-type ligands.
Organic and biomolecular chemistry, 2019Guanidines, which exist widely in nature, have been frequently utilised as strong Brønsted bases in organic chemistry. As ligands, guanidines can have different coordination modes with the metal center.

Redox-Active Guanidines and Guanidinate-Substituted Diboranes
2015Guanidino groups and guanidinate substituents are used to stabilise positive charges, both through mesomeric and through inductive effects. The interplay between several guanidino groups is employed to create redox-active compounds. One realisation concept leads to guanidino-functionalised aromatic compounds (GFAs), which comprise aromatic systems ...

Archives of Internal Medicine, 1939
In a recent article, 1 one of us (R. H. M.) presented the results of estimations of the "guanidine" content of the blood of 800 patients with arterial hypertension. An increase in blood "guanidine" was found in 32 per cent of hypertensive persons with normal values for nonprotein nitrogen in the blood and in a higher percentage of patients with ...
