Thiourea-based iminophosphorane (BIMP) organocatalysts featuring SPhos- or BIDIME phosphine units have been developed and successfully applied in the asymmetric addition of nitromethane to N-Boc-protected trifluoromethyl aryl ketimines. α-Trifluoromethyl β-nitroamines were obtained 40–82% isolated yields 80–95% enantioselectivities. A careful evaluation catalytic activity BIMPs indicates that c...

Twelve new imidazole-based potential bi- and tridentate ligands were synthesized and characterized. Whereas in the first series the alpha-amino acid and imidazole moieties were linked by an amino bond, in the second series the tridentate ligands, containing two imidazole groups, were separated by an amide bond. The first series was obtained by the reductive amination of 2-phenylimidazole-4-carb...

Medieval institutions contain an important strain of spontaneous order, especially from the pre-Christian period. A series of irregular successions after the Norman conquest made royal charters increasingly important in establishing the sovereign’s legitimacy. Henry I’s coronation charter (1100) formed the basis of Henry II’s aggressive program of reform legislation, as well as for Magna Carta ...

Our knowledge of the lives of our illustrious forebears and of local history in general would be limited and miscellaneous indeed had it not been for his painstaking research and scholarly writing which provided a record presented in orderly and artistic fashion. It is never possible to tell just ...
