New C-functionalized syn- and anti-dioxocyclam and cyclam derivatives with 1,2,3-triazole units attached to carbon atoms within the skeleton were designed as valuable bifunctional chelating agents for applications in nuclear medicine. These macrocyclic chelators were prepared via a multi-step sequence involving α- and β-amino acids, and their copper(ii) complexation properties were evaluated. A solution structure in which the triazoles are in axially coordinating positions was proposed for the [Cu(anti-27)]2+ complex. Promising results have been obtained regarding the complexation kinetics (1/2 = 3.21 d, 5 M HCl, 50°C).

The stereoselective allylation of acyclic chiral α-amino aldimines affording vicinal diamines, mediated by various Lewis acids (TiCl4, SnCl4, MgBr2·OEt2, BF3·OEt2, ZnCl2), is des

An effective 'promoter control' on enantioselective acyclic stereoselection based on chiral oxazaborolidinone-promoted asymmetric aldol reactions has been found in the case of chiral N-protected α-amino aldehydes. An enantioselective synthesis of the title compound has been efficiently accomplished by using a sequence of the aldol reaction. (C) 2000 Elsevier Science Ltd.
