During the alkylation of tertiary amines with ethylene chlorohydrin in aqueous solutions, the initial rates and degrees of conversion attained within control periods of time showed nonstandard dependences on the initial concentrations of reagents. The character of the concentration dependences depended on ...
To increase the reliability and success rate of drug discovery, efforts have been made to increase the C(sp3) fraction and avoid flat molecules. sp3-Rich enantiopure amines are most frequently encountered as chiral auxiliaries, synthetic intermediates fo

In the transalkylation of tertiary amines, unexpected higher yields are achieved requiring substantially less catalyst and much shorter reaction times at lower reaction temperatures using a homogeneous catalyst in the presence of an alcohol solvent and carbon monoxide. The process may be exemplified by ...
