- Latent Bronsted Base Solvent-Assisted Amide Formation from Amines and Acid Chlorides
-
Weakly basic amines, including even neutral amines such as nitroaniline and aminocarboxylic acids, react with acid chlorides very efficiently in N, N -dimethylacetamide (DMAC), without addition of a base, to give the corresponding amides in high yields. The role of DMAC and related solvents as latent Bronsted bases was studied in these amidation reactions. Less basic amines, such as aromatic amines, reacted with benzoyl chloride faster than more basic aliphatic amines.

- SAR based design of nicotinamides as a novel class of androgen receptor antagonists for prostate cancer
-
Molecular knowledge of pure antagonism and systematic SAR study offered a direction for structural optimization of DIMN to provide nicotinamides as a novel series of AR antagonists. Nicotinamides with extended linear scaffold bearing sterically bulky alkoxy groups on isoquinoline end were synthesized for H12 displacement. AR binding affinity and molecular basis of antiandrogenic effect establish the optimized derivatives, 7au and 7bb, as promising candidates of second generation AR antagonists for advanced prostate cancer.
