专利号:US-5420328-A 优先权日:1992-09-11 标题:Methods for the synthesis of phosphonate esters 发明人:CAMPBELL DAVID A 权利人:AFFYMAX TECH NV 摘要:Phsophonate esters can be synthesized in high yields by condensations of alcohols with methyl phosphonates followed by selective demethylation. The reaction is general, relativly insensitive to steric constraints of hindered phosphonic acids, and can also be carried out on a solid support to synthesize large collections of compounds to screen for pharmacological activity.
