Metal-ligand cooperation in the catalytic dehydrogenative coupling (DHC) of polyalcohols to carboxylic acid derivatives
Trincado, Monica,Kuehlein, Klaus,Gruetzmacher, Hansjoerg

Several polyols, which are easily available from sugars through biochemical conversion or hydrogenolytic cleavage, are directly converted into carboxylic acids and amides. This efficient dehydrogenative coupling process, catalyzed by a rhodium(I) diolefin amido complex, is an attractive approach for the production of organic fine chemicals from renewable resources. This method tolerates the presence of several hydroxy groups and can be extended to the direct synthesis of lactams from the corresponding amino alcohols under mild conditions.

supporting information; experimental part, p. 1499 - 1502 (2009/09/06)
1,2,4-Triazole anion has been identified as an active acyl transfer catalyst suitable for the aminolysis and transesterification of esters.
BASE-PROMOTED CYCLOCOUPLING REACTION OF 2-BROMOPROPANAMIDES AND 2-BROMOACETAMIDES WITH DMF

, p. 471 - 474 (2007/10/02)
In the presence of a suitable base, representative 2-bromopropanamides 4 and 2-bromoacetamides 5 undergo cyclocondensation onto the carbonyl group of DMF to yield the 2-(dimethylamino)oxazolidin-4-ones 6 and 10, respectively.Of these cyclic orthoester ami
