Methods for enantioselective 1,4-addition of main-group organometallics to linear enones are overviewed. Thiourethane and thioether 1,1′-binaphthyl-based ligands are effective for copper-catalysed 1,4-addition of ZnEt2 and AlR3 (R=Me, Et) to trans-

In the presence of chiral thiourethane ligands [Cu(MeCN) 4 ]BF 4 forms active catalysts for the conjugate addition of MeMgBr, ZnEt 2 and AlR 3 (R = Me, Et) to non-3-en-2-one, hept-3-en-2-one, and 5-methylhex-3-en-2-one. Enantioselectivities of up to

A convenient synthesis of TPPDS (disodium P-phenyl-3,3′-phosphinediyl-bis(benzenesulfonate)) from triphenylphosphine is described. This represents a quick and reliable way to prepare a water-soluble phosphine with essentially no phosphine oxide for
