“malonic ester amide synthesis” has been demonstrated, which uses α-substituted/unsubstituted diethyl malonates for the decarboxylative acylation of various aromatic/heteroaromatic primary/secondary amines to form one-carbon homologated amides, thus providing easy access to amides with odd/even chain lengths and an array of substituents on the alkyl/aryl part while avoiding use of acyl chlorides or peptide

improvements of the promiscuousamidaseactivity have been achieved for the carboxylic ester hydrolases compared to their natural activities, even though different sophisticated approaches of rational design have been applied. In the present study we used a combination of directed evolution and rational design to improve the promiscuousamidaseactivity of a Bacillussubtilisesterase. A double mutant
