Stereospecific Synthesis of a 2β-H-indoloquinolizidinone: Key Intermediate in Indole Alkaloids Synthesis

The pyranose 4 yielded the 2-oxa-8-aza-bicyclononane 14 by condensation with tryptamine 7; the intermediate acyliminium 18 led to the expected 2β-H-indoloquinolizidinone 15ab through a Pictet-Spengler cyclisation.Key Words: 2β-H-indoloquinolizidino
