A process for the preparation of compounds of formula ##STR1## or salt thereof where R.sub.1 is --X--Z and X is --C.tbd.C--, R.sub.2 and R.sub.2 ' are independently hydrogen, alkyl or trialkylsilyl; R.sub.3 is hydrogen or alkyl; and Z is a hydrophobic anchor; which includes reacting a compound of formula ##STR2## where R.sub.4 is alkyl, cycloalkyl or aryl; and R.sub.5 is trialkylsilyl or triarylsilyl with a compound of formula ##STR3## where Y is a halogen, to form a compound of formula ##STR4## and hydrolyzing the compound of formula IV to obtain the compounds of formula I. Compounds of formula I or salt thereof where R.sub.1 is --OR.sub.2 ' may be prepared by reacting a compound of formula III with a compound of formula P(OR.sub.2).sub.3 XII.
一种制备式为##STR1##的化合物或其盐的方法,其中R.sub.1为--X--Z,X为--C.tbd.C--,R.sub.2和R.sub.2'独立地为氢、烷基或三烷基硅基;R.sub.3为氢或烷基;Z为疏水锚点;包括将式为##STR2##的化合物(其中R.sub.4为烷基、环烷基或芳基;R.sub.5为三烷基硅基或三芳基硅基)与式为##STR3##的化合物(其中Y为卤素)反应,以形成式为##STR4##的化合物,并水解式为IV的化合物以获得式为I的化合物。式为I或其盐的化合物,其中R.sub.1为--OR.sub.2',可以通过将式为III的化合物与式为P(OR.sub.2).sub.3XII的化合物反应来制备。
