A series of fluorescent dolichyl phosphates containing the (1-naphthyl)amino group in the omega-fragment of the chain and possessing a definite distance between fluorophoric and phosphate groups were synthesized for studying the interactions of dolichyl phosphates with enzymes and biological membranes. The corresponding terminal 2,3-dihydrohexadeca-, 2,3-dihydroundeca-, and 2,3-dihydrooctaprenol epoxides were obtained from racemic dolichols (prepared from natural polyprenol mixtures) by van Tamelen epoxidation of their omega-isoprene unit and separated by preparative HPLC. These epoxides were converted to aldehydes, which were subjected to reductive amination with 1-aminonaphthalene and NaBH4 with subsequent phosphorylation of the resulting amino alcohols.
