Enzyme assisted synthesis of D-myo-inositol-1,2,6-trisphosphate

The title compound is prepared in enantiomerically pure form via a facile enzyme assisted route. Essential for the success of the described method were a) the highly enantioselective esterification of 4,6-O-dibenzoyl-myo-inositol 2, b) the selective acylation of the axial hydroxyl function in 3 and c) the selective, base catalysed methanolysis of one benzoate group in 5. The obtained, selectively protected 1,2,6-triol 6 was converted into the title compound 7 by phosphorylation using N,N-dimethyl dibenzyl phosphoamidite followed by deprotection.

Asymmetric synthesis and configurational stability of C2-symmetric hexacoordinated phosphate anions (TARPHATS) with predetermined chirality from tartrate esters

C2-Symmetric TARPHAT anions 5 made of a central Pv atom, one tartrato (=dialkyl 2,3-di(hydroxy-KappaO)butanedioato(2-)), and two tetrachloropyrocatecholato (=3,4,5,6-tetrachlorobenzene-1,2-diolato(2-)-KappaO,KappaO?) ligands can be easily prepared in decent to high yields (50-86%) as their dimethylammonium salt by using a one-pot process and simple commercially available starting materials. The presence of the chiral tartrato ligands (usually (2R,3R)) leads to the formation of diastereoisomeric anions ((Delta,2R,3R)/(Lambda,2R,3R)). Decent to good control by the chiral ligands-under equilibration conditions-over the Lambda or Delta configuration of the adducts was observed (d.r. 84:16 in CHCl3 for the di(tert-butyl) tartrate derivative), the selectivity depending on the nature of the ester chains as well as on the solvent.

Asymmetric IrI-catalysed allylic alkylation of monosubstituted allylic acetates with phosphorus amidites as ligands

Monodentate phosphorus amidites derived from 2,2?-binaphthol and a variety of chiral amines were employed as ligands in IrI-catalysed allylic alkylations of unsymmetrically substituted allylic acetates. The enantio- and regioselectivities of these reactions were investigated. Phosphorus amidites of bulky secondary chiral amines induced enantioselectivities of up to 94% ee in reactions of linear substrates. Phosphorus amidites derived from chiral primary amines, which have not been previously employed in asymmetric catalysis, furnished improved regioselectivities. The use of LiCl as additive led to improved regio- and enantioselectivities. ( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003).
