Synthesis of 5-Carbonyl-1,3-dihydro- 1,3-dioxo-2H-isoindole-2-propanoic Acid Integrin Antagonists
摘要:
The 5-carboxy-1,3-dihydro-1,3-dioxo-2H-isoindole-2-propanoic acid benzyl ester (1), obtained from condensation of 1,3-dihydro-1,3-dioxo-5-isobenzofuranearboxylic acid with beta-alanine benzyl ester p-toluenesulfonate, reacted with an appropriate amine (11) to afford the corresponding amide (IIIa-e) which then hydrogenolyzed by 5% palladium-on-carbon to give target compounds (IVa-e).
