  Asymmetric Synthesis of the Tropane Alkaloid (+)-Pseudococaine via Ring-Closing Iodoamination

  摘要：

  Ring-closing iodoamination of terf-butyl 2-hydroxy-7[N-methyl-N-(alpha-methyl-p-methoxybenzyl)amino]cyclohept-3-ene-1-carboxylates proceeds with concomitant loss of the N-alpha-methyl-p-methoxybenzyl group to give the corresponding 8-azabicyclo[3.2.1]octane scaffolds in >99:1 dr. Subsequent elaboration of one of these templates provided access to (+)-pseudococaine hydrochloride, in seven steps and 31% overall yield from commercially available starting materials.
