摘要
An enantioselective total synthesis of indolizidine 209D (1) from epoxy alcohol 4 is described. The key step in the sequence involves an aza-[2,3]-Wiltig rearrangement of vinylaziridine 7 to yield the cis-2,6-disubstituted tetrahydropyridine 8 in 98% yield and as a single detectable diastereomer.
