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.
Electochemical asymmetric dimerization of cinnamic acid derivatives and application to the enantioselective syntheses of furofuran lignans

A new electrochemical method for the asymmetric oxidative dimerization of cinnamic acid derivatives has been developed. This method enabled the enantioselective syntheses of furofuran lignans, yangambin, sesamin and eudesmin.

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

Brownbridge, Peter,Chan, Tak-Hang
, p. 3427 - 3430 (2007/10/02)
2,5-Bis(trimethylsiloxy)furan reacted with a number of substituted benzaldehydes under activation of titan tetrachloride to give 2,6-diaryl-3,7-dioxabicyclooctane-4,8-diones.
