Absolute Stereochemistry

A series of single enantiomer, 2,4-<i>cis</i>-disubstituted amino azetidines were synthesised and used as ligands for copper-catalysed Henry reactions of aldehydes with nitromethane. Optimisation of ligand substituents and the reaction conditions was conducted. The enantiomeric excess of the formed products was highest when alkyl aldehydes were employed in the reaction (>99% e.e.). The absolute stereochemistry of one representative azetidine derivative salt was determined by analysis of the Flack parameter of an XRD single crystal structure. The origin of selectivity in catalysis was investigated computationally, revealing the importance of the amino-substituent in determining the stereochemical outcome. A racemic platinum complex of a <i>cis</i>-disubstituted azetidine is examined by XRD single crystal structure analysis with reference to its steric parameters, and analogies to the computationally determined copper complex catalyst are drawn.<br>

In the title compound, μ-diphenylphosphido-μ-hydrido-bis[bromido(triphenylphosphane-κP)platinum(II)] diethyl ether monosolvate, [Pt2Br2(C12H10P)H(C18H15P)2]·C4H10O or [Pt2(μ-H)(μ-PPh2)Br2(PPh3)2]·(C2H5)2O, the PtII atoms are coordinated in a distorted square-planar arrangement, with one hydrido and one phosphido ligand bridging in a trans position. In the lattice, C—H...·O and C—H...π interactions are present. This complex has a total number of 32 electrons, 16 electrons for each PtII atom. One of the Br atoms is disordered over two positions in a 0.92:0.08 ratio.
