Abstract: A new composition of matter comprising molybdenum trioxide and heterocyclic nitrogen or oxygen Lewis bases. The molybdenum trioxide, upon reaction with Lewis base, forms a layered compound characterized in that the Lewis base is covalently bonded to molybdenum atoms in molybdenum oxide layers. The layered compound has the formula LMoO.sub.3 where L is a Lewis base containing nitrogen or oxygen electron donors and selected from the group consisting of 5- and 6-membered heterocyclic amines, amine oxides, triorganophosphates, phosphine oxides and sulfoxides. L has the steric requirement such that its cross-sectional area perpendicular to an axis running through the L-Mo covalent bond is less than about 30(A).sup.2.

Abstract: Process for the homogeneous catalytic hydrogenation of .beta.-substituted-.alpha.-acylamido-acrylic acids which yields, after hydrogenation, an optically active mixture. The process comprises the hydrogenation of .beta.-substituted-.alpha.-acylamido-acrylic acids in the presence of an optically active coordinated metal complex hydrogenation catalyst, in which the metal is selected from the group consisting of rhodium, iridium, ruthenium, osmium, palladium and platinum.This process is a generalized process for any asymmetric hydrogenation of .beta.-substituted-.alpha.-acylamido-acrylic acids in which one .alpha.-amino acid enantiomorph is the desired end-product. It is especially useful for the preparation of .alpha.-amino acids found in nature which possess optical activity and which have a hydrogen attached to the asymmetric center.This invention also relates to new optically active coordinated metal complex hydrogenation catalysts.
