Investigation of proline amides and pyridinium salts as catalyst for direct aldol reactions in water
The catalytic potential of chiral proline amides and pyridinium salts in the aldol condensation in water was investigated. The aldol reactions of acetone with various aromatic aldehydes were carried out in water by using proline amide derivatives and pyri

Aminophosphinic acids in a pyridine series, Part 2: Synthesis of 2-, 3-, and 4-pyridyl derivatives of 1-(Benzylamino)-methyl-H-phosphinic Acids
New 2-pyridyl, 3-pyridyl, and 4-pyridyl derivatives of 1-[N-(benzyl)amino]- methyl-H-phosphinic acid were prepared by the addition of bis(trimethylsilyl) phosphonite to the corresponding imines and subsequent methanolysis of the addition products. Treatment of the 2-pyridyl- and 1-(4-pyridyl)-1-(benzylamino) -methyl-H-phosphinic acids with aqueous mineral acids leads to cleavage and formation of the corresponding secondary amines and phosphorous acid (H3PO3).
