Mild N-deacylation of secondary amides by alkylation with organocerium reagents
Secondary amides are a class of highly stable compounds serving as versatile starting materials, intermediates and directing groups (amido groups) in organic synthesis. The direct deacylation of secondary amides to release amines is an important transformation in organic synthesis. Here, we report a protocol for the deacylation of secondary amides and isolation of amines. The method is based on the activation

We report the synthesis of new protic ionic liquids (PILs) based on aniline derivatives and the use of high-throughput (HT) techniques to screen possible candidates.
A novel series of ten substituted 4H-pyrimido [2,1-b] [1,3] benzothiazole curcumin derivatives
have been synthesized and evaluated for their antimicrobial activity against Gram positive and
Gram negative bacteria viz. Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus cereus and
against fungi viz. Alternaria solani, Aspergillus niger, Fusarium culmorum and Rhizopus stolonifer.
The mechanism involves condensation of substituted benzaldehyde and curcumin via Knovenegal reaction
which further reacts with substituted benzothiazole through Michael addition in the presence of
pyridine catalyst using methanol as a solvent. The synthesized compounds were analyzed by elemental
and spectral analysis.
