Total synthesis of lembehyne A, a neuritogenic spongean polyacetylene
摘要:
The first total synthesis of lembehyne A, a neuritogenic polyacetylene from a marine sponge Haliclona sp., was achieved by utilizing alkyne formation with dimethyl-l-diazo-2-oxopropylphosphonate and asymmetric reduction with Alpine-borane as the key reactions.

Lembehyne A, a Novel Neuritogenic Polyacetylene, from a Marine Sponge of Haliclona sp.
Lembehyne A (1), a novel long chain polyacetylene, which induces neurite outgrowth, was isolated from a Indonesian marinesponge of Haliclona sp. The total structure of 1 was determined by spectroscopic study, chemical degradation, and modified Mosher's method. Lembehyne A induced neuritogenesis in pheochromocytoma PC12 cells and neuroblastoma Neuro 2A cells at 2 and 0.1 μg/mL, respectively.
