Tricycloillicinone (1), a novel tricyclic prenylated C6-C3 compound, has been isolated as a neurotrophic substance from the woods of Illicium tashiroi and its structure has been elucidated by spectroscopic analyses. Compound 1 could increase ChAT activity in culture of P10 rat septal neurons.

α-Glycosyl phosphates and 4-phosphates of N-acylglucosamine derivatives were prepared in high yields via the reaction of corresponding O-lithium salts with dibenzyl or diphenyl phosphorochloridate at low temperature.
