In the past, hemlock poisoning was only known for its neurotoxic effects; quite recently non-neurological features, consisting of rhabdomyolysis and acute renal failure, have been also described. Here we report our experience with these clinical findings, which we frequently observe...

[reaction: see text] Sequences of lithiation-substitution, enantioselective hydrogenation, and diastereoselective lithiation-substitution provide efficient highly enantioselective syntheses of 2-substituted and cis and trans 2,6-disubstituted piperidines. The methodology is demonstrated by syntheses of (-)-coniine, (-)-solenopsin A, and (-)-dihydropinidine as their hydrochlorides.

(S)-Coniine is made using a reaction which assembles the piperidine ring by the sequential formation of four new chemical bonds and installs the C-2 stereogenic centre with high levels of diastereocontrol (90% de).
