  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.

  使用DMF作为催化剂和助溶剂进行多元醇和二元醇的区域选择性硅烷化

  摘要：

  尽管使用DMF作为溶剂的甲硅烷基化已超过40年，但已发现DMF是未保护碳水化合物在区域选择性甲硅烷基化中的良好催化剂。已经证明，可以在TBSC1和DMF之间形成具有1：1比例的结合配偶体的复合物，并且其缔合常数为12 / M，从而激活甲硅烷基化。

• From organocatalysed desilylations to high-yielding benzylidenations of electron-deficient benzaldehydes

  A new type of organoprecatalyst (MeSCH2Cl/KI) for desilylation and benzylidenation reactions has been designed. Both reactions are user friendly and high yielding (71–>99%) and have fast reaction rates. The desilylation of iodo silyl ethers was achieved with no sequential etherification side reactions like those seen for reactions when using TBAF. In the application of the catalytic system to a 6-TBDMS

  设计了一种用于脱甲硅烷基化和亚苄基化反应的新型有机预催化剂（MeSCH2Cl/KI）。两种反应都对用户友好且产率高 (71–>99%)，并且反应速度快。碘甲硅烷基醚的脱甲硅烷基化是在没有像使用 TBAF 的反应中看到的那样的连续醚化副反应实现的。在将催化系统应用于葡萄糖苷的 6-TBDMS 醚时，使用缺电子苯甲醛的葡萄糖苷苄基化以 87% 的产率实现，而先前报道的产率为 69-77%。总共使用甲硅烷氧基醇和缺电子苯甲醛代替它们的活化缩醛形式实现了 14 次苯亚甲基化反应。在反应速率和产率方面，苯亚甲基化的顺序是对氟苯甲醛>苯甲醛> 对茴香醛，并讨论了可能的机制。这些实验初步将这种具有成本效益的催化系统与经典的路易斯酸区分开来。
• Using DMF as Both a Catalyst and Cosolvent for the Regioselective Silylation of Polyols and Diols

  discovered to be a good catalyst in the regioselective silylation of unprotected carbohydrates, although the silylation using DMF as a solvent has been a common method for more than 40 years. It has been demonstrated that a complex with a 1:1 ratio of the binding partners can be formed between TBSCl and DMF and has an association constant of 12/M, thus activating the silylation.
