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.
The amino acid derivative of the present invention provides a novel compound that shows excellent analgesic action. The amino acid derivative of the present invention is a novel compound that shows excellent analgesic action to not only a model animal for nociceptive pains but also a model animal for neuropathic pains, so that the amino acid derivative is very useful as a drug for treating various pain diseases.
