A simple approach to the synthesis of dolichyl phosphate derivatives with a fluorescent label, 2-aminopyridine residue, at the omega -end of the chain was developed. The method includes selective van Tamelen epoxidation of the omega -isoprene unit in dolichyl acetates, transformation of the epoxides to omega -terminal aldehydes, their reductive amination, and phosphorylation of the resulting amino alcohols.
