Total synthesis of sapinofuranone A from d-ribose

The total synthesis of sapinofuranone A has been achieved starting from naturally occurring carbohydrate d-ribose via a short and high yielding route. The key transformations include Wittig olefination, Ohira–Bestmann reaction, Sonogashira coupling. Finally acetonide deprotection and subsequent lactonization using catalytic amount of hydrochloric acid completed the total synthesis of sapinofuranone A.
