A convenient synthetic route to mannose 6‐phosphonate—cholesteryl conjugate

A multistep synthesis of a mannose 6‐phosphonate‐based glycolipid is described involving (1) a one‐carbon chain elongation at the 6‐position of mannose, followed by (2) phosphonation, using tris(trimethylsilyl)phosphite. This method was shown to e efficient and provides a general route to various mannose 6‐phosphonate‐based compounds for the design of drug delivery systems. © 2003 Wiley Periodicals, Inc.
