  Conformational Control of Flexible Molecules:  Design and Synthesis of Novel Chiral 1,5-Diaza-cis-decalins

  摘要：

  Control of the conformational equilibria of 1,5-diaza-cis-decalins, a new class of chiral diamine ligands, has been investigated. Chiral 2,6- and 3,7-substituted derivatives of 1,5-diaza-cis-decalins were designed to stabilize the conformational form needed to chelate a lithium. These derivatives were synthesized in optically pure form starting from 1,5-diaza-cis-decalin. Due to the rigid and conformationally well-defined nature of these compounds, the potential of these compounds as chiral diamine ligands was investigated. Asymmetric lithiation-substitution reactions of N-Boc-pyrrolidine and N,N-diisopropyl-o-ethylbenzamide were performed using these ligands and up to 60% ee was obtained. For the latter substrate, results spanning a range from 32% ee (R) to 60% ee (S) were obtained (Deltaee = 92%) with 1,5-diaza-cis-decalin ligands differing only in the location of two methyl substituents. Unlike many other diamines that have been employed in asymmetric lithiation-substitution reactions, the limited conformational flexibility of the 1,5-diaza-cis-decalins is analogous to (-)-sparteine such that these results may permit the construction of structure-activity relationships.

  Synthesis and conformational analysis of 2,6-dimethyl-1,5-diaza-cis-decalins

  摘要：

  The stereoselective synthesis of 2,6-dimethyl-1,5-diaza-cis-decalins with the dimethyl groups syn or anti to the angular hydrogens has been accomplished starting from 1,5-diaza-cis-decalin. From an NMR study of the conformational properties of all three 2,6-dimethyl-1,5-diaza-cis-decalins, the components which affect the conformational equilibrium have been identified.

  developed. A wide range of 1,5‐naphthyridine derivatives were efficiently hydrogenated to give 1,2,3,4‐tetrahydro‐1,5‐naphthyridines with up to 99 % ee and full conversions. This facile and green protocol is applicable to the scaled‐up synthesis of optically pure 1,5‐diaza‐cis‐decalins, which have been used as rigid chelating diamine ligands for asymmetric synthesis.

• Homogeneous Perdehydrogenation and Perhydrogenation of Fused Bicyclic N-Heterocycles Catalyzed by Iridium Complexes Bearing a Functional Bipyridonate Ligand

  Homogeneous perdehydrogenation of saturated bicyclic 2,6-dimethyldecahydro-1,5-naphthyridine and perhydrogenation of aromatic 2,6-dimethyl-1,5-naphthyridine with release and uptake of five molecules of H-2 are efficiently achieved by iridium complexes bearing a functional bipyridonate ligand. Successive perhydrogenation and perdehydrogenation of 2,6-dimethyl-1,5-naphthryridine using a single iridium complex also proceed with the reversible inter-conversion of the catalytic species, depending on the presence or absence of H-2.
