A novel, efficient and atom economical onepot protocol for the synthesis of N-(β-nitro)amides has been described by combining the Henry reaction with the Ritter reaction. The designed products could be obtained from easily available aldehydes, nitroalkanes and nitriles with 60–83% overall yields under mild reaction conditions. In addition, the product can easily be transformed into diamine or protective
This invention relates to novel compounds which are ACAT inhibitors rendering them useful in lowering blood cholesterol levels. The compounds contain two urea or thiourea, amide, or amine moieties or combinations of said moieties and have the following general formula:
wherein Ar is an aryl group, m and n are zero or one, W and YNH and
form the urea, thiourea, amide or amine moieties.
