From theresults in the Table-1, it can be seen clearly that thecatalysts, especially catalyst 6, have good catalyticactivity in the direct aldol reaction of acetone with different aldehydes in water and the catalysts 7 and 8 show better asymmetric induction than catalyst 6.
The catalytic activities of pyridinium salts were also investigated starting with the aldol reaction of acetone with 4-nitrobenzaldehyde.

These compounds were used for aldol reaction as catalyst for the first
Using these proline amides and pyridinium salts as catalysts in aldol reaction is also important from the viewpoint of green chemistry, because of using environmentally friendly solvent water.
Logically organized by reaction type, the sections focus on [3,3]-sigmatropic rearrangements, aldol reactions, metal allylation reactions, stereoselective reductions, and other reactions.
Duthaler spoke about the use of cyclopentadienyltitanium-TADDOLS to mediate enantioselective additions of organolithium species to carbonyls and to effect aldol reactions as well as additions of allyl titanium species to carbonyls.
