The efficient and expeditious syntheses of both enantiomers of the amphibian alkaloid cis-225H have been achieved. Utilizing a common cis-2,5-disubstituted pyrrolidine building block derived from (+)-2-tropinone, the enantioselective syntheses have established the absolute configuration of these alkaloids as (+)-(2R,5S) and (−)-(5S,2R).
