Protecting-Group-Free Total Synthesis of (−)-Rhazinilam and (−)-Rhazinicine using a Gold-Catalyzed Cascade Cyclization
‘Rhaz'zmatazz: A totalsynthesis of (−)‐rhazinilam and the first asymmetric totalsynthesis of (−)‐rhazinicine were accomplished by using constructing the indolizinone core through the gold‐catalyzed cyclization of a fully elaborated linear ynamide. The scope and generality of this cascade reaction for the construction of highly substituted indolizinones were also investigated.

The present invention relates to a process for the preparation of α-chloroketones from readily available alkyl esters by the reaction of a sulfoxonium ylide on said alkyl esters to generate a keto sulfoxonium ylide that is in turn treated with anhydrous HCl.

Imines and carboxylic acids have been directly coupled using propylphosphonic acid anhydride and NEt(i-Pr)2 to give N-acyliminium ions, which were intramolecularly trapped with oxygen, nitrogen, sulfur, and carbon nucleophiles to provide a wide range of structurally diverse heterocycles.
