Preparation and Synthetic Applications of N-(α,β-Unsaturated Acyl)-α-amino Acid Derivatives
摘要:
N-(alpha,beta-Unsaturated acyl)-alpha-amino acids, amides and esters are structural motifs of many biologically active natural products. An alternate and advantageous approach for the synthesis of N-(alpha,beta-unsaturated acyl)-alpha-amino acid derivatives is developed via acylation of unprotected alpha-amino acids with stable crystalline N-(alpha,beta-unsaturated acyl)benzotriazole. The proposed methodology provides a new synthesis for compound (9) which is a precursor to a novel cytotoxic agent.

inhibitors of guinea pig liver transglutaminase. The most effective inhibitors evaluated can be sorted into two subclasses: substituted cinnamoyl benzotriazolyl amides and the 3-(substituted cinnamoyl)pyridines, referred to more commonly as azachalcones. Kinetic evaluation of both of these subclasses revealed that they display reversible inhibition and are competitive with acyldonor TGase substrates at IC50
