  Synthesis of Rosavin and its analogues based on a Mizoroki-Heck type reaction

  摘要：

  The Rosavin framework could be constructed with either phenylboronic acids, the protected arabinopyranosyl bromide 4 or the protected xylopyranosyl bromide 5, along with allyl O-beta-D-glucopyranoside 7 that could be easily prepared based on direct beta-glucosidation between allyl alcohol and D-glucose using the immobilized beta-glucosidase (EC 3.2.1.21). The key reaction was the Pd(II)-catalyzed Mizoroki-Heck type reaction between allyl beta-D-glucopyranoside congeners 9 or 10 and arylboronic acids. Deprotection of the coupling products afforded synthetic Rosavin 1, 4-methoxycinnamyl 6-O-(alpha-L-arabinopyranosyl)-beta-D-glucopyranoside 2, and cinnamyl 6-O-(beta-D-xylopyranosyl)-beta-D-glucopyrano side 3, which were identical with the natural products in respect to the specific rotation and spectral data.
