and (±)-debromoisolaurinterol 8 are described. Key features are a diastereoselective, sulfur mediated radicalcyclisation of diene 12 to give 35; a newradical to polar crossover sequence mediated by Bu3Sn that transforms diene 12 into (±)-debromoisolaurinterol 8; and a series of biomimetic cyclisation and oxidation reactions.

Thioamides may be transformed into thioesters through the simple expedient of warming them in an aqueous THF solution containing an alkylating agent. Reactions proceed in high yield and are amenable to multi-gram scale.

Resin bound thioesters can be prepared by heating thioamides in aqueous DMF with Merrifield resin in the presence of sodium iodide. These thioamides can be cleaved to give alcohols, ketones and lactones by a variety of methods.
