The novel bis-addition of benzaldehydes to acrylates or maleates was achieved by the direct use of samarium metal with the assistance of CuI under mild conditions under dry air, and the useful 2-hydroxylalkyl-γ-butyrolactons and lignan derivatives were thus constructed with high efficiency. The key factors that influence the reaction efficiency were investigated. The use of potassium iodide and molecular sieves as additives can improve the reaction efficiency remarkably.

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.
