Enantioselective synthesis of quaternary α-aminophosphonates via conjugate addition of α-nitrophosphonates to enones

Enantioselective Michael addition of α-nitrophosphonates to enones for the synthesis of α-aminophosphonates is reported for the first time. The reaction proceeds in good to high yields and moderate to high selectivity in the presence of a new quinine thio

Catalytic asymmetric synthesis of α,β-disubstituted α,γ-diaminophosphonic acid precursors by michael addition of α-substituted nitrophosphonates to nitroolefins

Michael additions of α-substituted nitrophosphonates to various nitroolefins are shown to proceed with high diastereo- and enantioselectivity when catalyzed by a quinine-derived thiourea-tertiary amine bifunctional catalyst and generate α,γ-diaminophosphonic acid precursors with contiguous quaternary and tertiary stereocenters.

Synthesis and structural properties of metal complexes of dialkyl α-hydroxyiminophosphonates

A range of dialkyl α-hydroxyiminophosphonates R'C=N(OH)P(O)(OR)2, with substituents of varying bulk (R=Et, R'=Me L1, Et L2, c-Pr L3, 3-heptyl L4; R=i-Pr, R'=Et L5, 3-heptyl L6; R=n-Bu, R'=Pr L7) have been used to synthesise neutral metal complexes with nickel(II)[Ni(L1-3,5)Cl2], cobalt(II) [Co(L1-3,5)Cl2] and lanthanides (La(III) with L1,2,5, Pr(III) with L1,2,4-7, Nd(III) with L5, Gd(III) with L2,5 and Dy(III) with L2,5) the charge being balanced by anionic ligands chloride or nitrate. Included in this range are two 3-heptyl derivatives which have not previously been reported. All the metal complexes have been fully characterised by elemental analysis, IR, electronic and NMR spectroscopy and mass spectrometry. X-Ray crystallography has been used to establish the structure of six key metal complexes and one of the free ligands (L3). Three different bonding modes have been established. The d-block metal chlorides consistently show symmetrical bidentate coordination in [ML2Cl2], the lanthanide chlorides [ML3Cl3] are all asymmetrically bidentate and monodentate coordination was observed in the neodymium nitrate complex [NdL52(NO3)3(H2O)].
