Tailor-Made Silylating Agents for Efficient Surface Modification
摘要:
N-硅基二甲基胺是对羟基二氧化硅制剂进行化学表面改性的高效硅烷化剂。本文介绍了氯(5-X-3,3-二甲基戊基)-二甲基硅烷的合成及其转化为相应的(二甲基氨基)硅烷的过程,其中 X 是甲氧基、甲氧基甲氧基、氰基或二甲基氨基。笨重的取代基在表面形成了两级保护层。第二层保护层阻碍了亲核物进入硅原子,从而提高了水解稳定性。
The iodine/DMAP-mediated intramoleculartandem C–C/C–O bond forming reaction of malonate bearing alkene moiety proceeded to give bicyclic lactones with good diastereoselectivity in good yield. The mechanistic investigation was also discussed on the basis of various control experimental results.

A new Pd(II)-catalyzed cascade sequence for the formation of polyheterocycles, from simple starting materials, is reported. The sequence is applicable to both indole and pyrrole substrates, and a range of substituents are tolerated. The reaction is thought to proceed by a Pd(II)-catalyzed C–H activated Heck reaction followed by a second Pd(II)-catalyzed aza-Wacker reaction with two Cu(II)-mediated
