Stereochemistry of phellinsin A: A concise synthesis of α-arylidene-γ-lactones

Phellinsin A (1a) was prepared in a concise way, thereby elucidating the relative stereochemistry of the aryl and carboxylic acid groups in 1a. The synthesis employed selective monohydrolysis of the dilactones derived from oxidative dimerization of cinnamic acid derivatives. This approach provided a practical synthetic route to α-arylidene-γ-lactones. Copyright Taylor & Francis, Inc.

Oxidation of p-alkoxycinnamic acids either with thallium(III) trifluoroacetate in TFA/CH2Cl2 or with cobalt(III) trifluoride in CH3CN, in the presence of a small amount of BF3*Et2O, results in instantaneous oxidative dimerization to give the bislactone li
