Enantioselective synthesis of the AB ring system of aklavinone via a chemoenzymatic route
摘要:
The AB ring system 2 of aklavinone 1 was obtained using a chemoenzymatic protocol. Key steps are the stereoselective addition of lithium enolate of ethyl acetate to ketone 13 and the intramolecular Friedel-Crafts reaction to give tetralin 17.
