Versatile construction of functionalized tropane ring systems based on lactam activation: enantioselective synthesis of (+)-pervilleine B.
نویسندگان
چکیده
The halo-assisted intramolecular addition of silyl enol ethers with in situ activated lactams yielded (hydroxylated) 1-halo-8-azabicyclo[3,2,1]octane and 1-halo-9-azabicyclo[3,3,1]nonane ring systems, which provided an easy enantioselective access to 6β-silyloxytropane-3-one, 3α,6β-dihydroxytropane, and pervilleine B. The absolute configuration of the natural (-)-pervilleine B was determined to be 1R,3R,5S,6R.

متن کاملA new method for the construction of the hydroxylated tropane skeleton: enantioselective synthesis of (-)-Bao Gong Teng A.
An efficient and highly diastereoselective method for the construction of the hydroxylated tropane skeleton is described. The method features a new intramolecular reductive coupling reaction of N-acyl N,O-acetal with aldehyde, cooperatively mediated by BF(3)·OEt(2) and SmI(2). On the basis of this method, a new enantioselective total synthesis of (-)-Bao Gong Teng A has been accomplished.
