Brønsted acids (Chiral LBBAs) have been designed as new organocatalysts for biomimeticenantioselectivecyclization. A salt of a chiral phosphonous acid diester with FSO3H catalyzes the enantioselectivecyclization of 2-geranylphenols to give the desired trans-fused cyclized products with high diastereo- and enantioselectivities (up to 98:2 dr and 93% ee).

hit containing stilbene scaffold 5 which on initial optimization gave us a vinyl stilbene compound 16c (EC50 = 4.4 μM). Herein we report our structure-activity relationship study of the novel series of vinyl stilbene analogs that inhibits viral RNA genome replication in a human NV-specific manner. Among these newly synthesized compounds, several amide derivatives of vinyl stilbenes exhibited potent

and efficient syntheses of the naturally occurring ugonstilbenes A, B, and C. The stilbene skeleton was prepared using the Horner–Wadsworth–Emmons reaction. On the basis of their specific rotations, the absoluteconfigurations of ugonstilbenes A and C were both determined to be R, while the absoluteconfiguration of ugonstilbene B was determined as 4aS,9aR. The synthesized compounds showed cytotoxic
这项研究描述了天然存在的二苯乙烯 A、B 和 C 的首次有效合成。二苯乙烯骨架是使用 Horner-Wadsworth-Emmons 反应制备的。根据比旋光度,确定乌二苯乙烯 A 和 C 的绝对构型均为R,而乌二苯乙烯 B 的绝对构型确定为 4a S,9a R。合成的化合物对选定的人类癌细胞系表现出细胞毒活性。
