Method for the preparation of polyphosphorylated derivatives of galactopyranosides with a potential insulin-like activity.

摘要

Process for the preparation of polyphosphorylated galactose derivatives with an insulin-like activity wherein in a first step partially prectected alkyl alpha - or beta - @ <EMR ID=14.0>-galactopyranosides or derivatives thereof containing two or three free hydroxyl groups are phosphitylated; in a second step the so obtained partially phosphitylated derivatives are oxidized to the partially phosphatated derivatives which in the third step are deprotected to the corresponding free phosphates which are isolated in the form of the sodium salt.
