A simple, inexpensive, step economic, and highly modular synthetic strategy to access izidine alkaloids is described. The key step is a TfOH-promoted intramolecularaldolcondensation between enol and cyclic imide moieties. This cyclization strategy can be employed within an aza-Robinson annulation framework and represents a general tool to build fused bicyclic amines. To illustrate the power of this

The synthesis of 8,8a-trans-8-hydroxy-indolizidine 12 from (D,L)-pipecolinic acid by two alternative routes is described. The stereospecific decarbonylation of the bicyclic carboxyamide 9 promoted by diphenylphosphorazidate (DPPA) is the key step of our strategy. The bicyclic enamide 10 is described as a valuable intermediate in the synthesis of hydroxylated indolizidines.
