Pyrrolizidines, indolizidines and quinolizidines via a double reductive cyclisation protocol: concise asymmetric syntheses of (+)-trachelanthamidine, (+)-tashiromine and (+)-epilupinine
The asymmetric syntheses of pyrrolizidine, indolizidine and quinolizidine alkaloids have been achieved using the diastereoselective conjugate addition of lithium (R)-N-benzyl-N-(α-methylbenzyl)amide to α-alkenyl-α,β-unsaturated esters followed by diastereoselective protonation of the resultant enola...
