  Stereocontrolled synthesis of 2-aryl tetralones. Application in the synthesis of B/C hexahydrobenzo[c]phenanthridine alkaloids

  摘要：

  Hexahydrobenzo[c]phenanthridines possessing a B/C cis ring junction have been synthesized in a stereoselective way starting from chiral non-racemic 2-aryl-tetralones prepared by asymmetric alkylation of (+)-(S,S)-pseudoephedrine based arylacetamide enolates with appropriately functionalized 2-aryl-1-iodoethane electrophiles. Subsequent transformations (intramolecular Friedel-Crafts acylation, stereocontrolled reductive amination and Pictet-Spengler cyclization) yielded the target heterocycles in good overall yields and in excellent stereoselectivities.
