The invention relates to a method of preparing urethane-protected N-carboxyanhydrides of alpha amino acids. The inventive method enables the synthesis of urethane-protected N-carboxyanhydrides of alpha amino acids in the presence of a catalytic quantity of triethylene diamine without the addition of a tertiary amine-type base.
The present invention relates to 5-substituted-4-(substituted)phenylamino-2-pyridone derivatives, pharmaceutical compositions and methods of use thereof.
The present invention relates to 5-substituted-4-(substituted)phenylamino-2-pyridone derivatives, pharmaceutical compositions and methods of use thereof.
The nickel-catalyzed three-component reductive carbonylation of alkylhalides, aryl halides, and ethyl chloroformate is described. The use of ethyl chloroformate as a safe and readily available source of CO provides an efficient and practical alternative for the synthesis of aryl-alkyl ketones.
