Intramolecular Aldol Reaction of N-Acylated (2-Aminophenyl)-α-oxoacetic Acids: Rapid Access to Tri- and Tetracyclic 1,2-Dihydroquinolin-2(1H)-ones
摘要:
A four-step synthesis of tri- and tetracyclic 1,2-dihydroquinolin-2(1H)-ones via acylation of various substituted isatins with readily available N-Boc-protected amino-acids followed by an intramolecular aldol reaction and cyclization has been developed. The final products were obtained in moderate to excellent overall yields.
