Method for synthesizing artificially all-trans-resveratrol and derivative thereof
-
Paragraph 0069; 0070, (2017/08/31)
The invention discloses a method for synthesizing artificially all-trans-resveratrol and a derivative thereof. In the method, the precursors of all-trans-resveratrol and the derivative thereof are prepared by means of constructing a conjugated fused ring, thus the all-trans-spatial structure of resveratrol and the derivative thereof is restricted completely, to prepare all-trans-resveratrol and the derivative thereof. The resulting product of the preparation method of 1,2-stilbene or the derivative thereof in the invention is of all-trans configuration, so as to meet the demand of biologically active substance chemicals. Compared to the previous processes, the method provided by the invention has the advantages of simple processes and mild conditions, thereby meeting the green chemistry concept.

trans-Resveratrol (1a) is a phytoalexin produced by plants in response to infections by pathogens. Its potential activity against clinically relevant opportunistic fungal pathogens has previously been poorly investigated. Evaluated herein are the candidacidal activities of oligomers (2a, 3-5) of 1a purified from Vitis vinifera grape canes and several analogues (1b-1j) of 1a obtained through semisynthesis using methylation and acetylation. Moreover, trans-ε-viniferin (2a), a dimer of 1a, was also subjected to methylation (2b) and acetylation (2c) under nonselective conditions. Neither the natural oligomers of 1a (2a, 3-5) nor the derivatives of 2a were active against Candida albicans SC5314. However, the dimethoxy resveratrol derivatives 1d and 1e exhibited antifungal activity against C. albicans with minimum inhibitory concentration (MIC) values of 29-37 μg/mL and against 11 other Candida species. Compound 1e inhibited the yeast-to-hyphae morphogenetic transition of C. albicans at 14 μg/mL.

, p. 1319 - 1324 (2007/10/03)
Two variants of synthesis of resveratrol (3,5,4′ -trans-trihydroxystilbene) from dimethyl ether and anisaldehyde were performed using the chromium η6-benzenetricarbonyl complex. The Wittig-Horner reactions or aldol condensation in four stages followed by demethylation by EtSLi were applied.
