- A Facile and Highly Stereoselective Synthesis of Trichonine by Two Consecutive Reactions of Arsonium Salts
-
Trichonine (5) has been synthesized from 1-hexadecanal (1) by two steps of consecutive olefination, in which formylmethyltriphenylarsonium bromide (2) and (pyrrolidinecarbonyl)methyltriphenylarsonium bromide (4) were used in the presence of potassium carbonate.The product was obtained in pure (2E,4E) configuration, and the overall yield reached 87percent.
