atoms, has been realized for the first time. A series of optically active bicyclo[3.2.1]octanes bearing chiral quaternary and tertiary carbon stereocenters were obtained in good yields with excellent enantioselectivities, exhibiting good functional‐group tolerance and scalability. Moreover, deuterated optically active bicyclo[3.2.1]octanes were also obtained in high efficiency.

A variety range of functionalized aryl and heteroaryl zinc reagents were efficiently generated by using TMP2Mg center dot 2LiCl (TMP = 2,2,6,6-tetramethylpiperamidyl) in the presence of ZnCl2. The subsequently functionalization gave after reaction with electrophiles the expected polyfunctionalized products in good yields. A detailed study concerned on the point how we found the protocol and how we optimized it was depicted. (C) 2009 Elsevier B.V. All rights reserved.
