  Synthesis of 4-O-[3-(aryl)prop-2-ynyl]-Neu5Ac2en and its 4-epi-analogs modified at C-4 by Sonogashira coupling reaction

  摘要：

  To explore new inhibitors of the sialidase of human parainfluenza virus type 1 (hPIV-1), a series of novel Neu5Ac2en derivatives were synthesized. Thus, 8,9-O-isopropylidene-4-O-2-propynyl-Neu5Ac2en methyl ester 8 was subjected to a Sonogashira coupling reaction with a variety of heteroaryl halides to produce a series of 4-O-(3-heteroaryl-2-propynyl) compound 9. Treatment of 9 with 80% acetic acid followed by alkaline hydrolysis afforded deprotected Neu5Ac2en compounds. The 4-epi-analogs of this type of Neu5Ac2en were synthesized in a similar manner. Compound 5d showed the most potent inhibitory activity (IC50 1.2 mu M) against hPIV-1 sialidase. (C) 2007 Elsevier Ltd. All rights reserved.
