A highly basicphosphine, tris(2,4,6-trimethoxy phenyl)phosphine (TTMPP), catalyzes cyanomethylation using trimethylsilylacetonitrile (TMSCH2CN) to give the corresponding products in good to high yields, with both carbonyl compounds and imines.
Catalytic cyanomethylation of various carbonyl compounds with (trimethylsilyl)acetonitrile (TMSCH2CN) in the presence of Lewis bases such as cesium or lithium acetate proceeded smoothly to afford t...

This invention relates to novel compounds of the Formula (I), (Ia), (Ib), (Ic), (Id), (Ie), (If), (Ig), (Ih); (Ii); (Ij), (Ik), (II) pharmaceutically acceptable salts thereof, and pharmaceutical compositions thereof, which are useful for the therapeutic treatment of diseases associated with the modulation or inhibition of 11 β-HSD1 in mammals. The invention further relates to pharmaceutical compositions of the novel compounds and methods for their use in the reduction or control of the production of cortisol in a cell or the inhibition of the conversion of cortisone to cortisol in a cell.
Organozinc compounds derived from α-bromonitriles are readily prepared in solution in tetrahydrofuran (THF) and exist in the C metallated form. They condense normally with aldehydes and saturated ketones. A number of new β-hydroxy-nitriles are described. The addition of conjugated unsaturated ketones results in the formation of β-hydroxynitriles or ketonitriles, depending on the nature of the initial
