Odd Couple: A method for the synthesis of alkaloid‐pyrones using a novel pyrone annulation of β‐carbolines and indoles with 3‐siloxy‐4‐pyrones is reported. The approach has enabled synthesis of the unusual alkaloid‐pyrone pleiomaltinine from the plant‐derived indole‐alkaloid pleiocarpamine (see Scheme; TBS= tert‐butyldimethylsilyl).
