Truxinate Org Syn Prep

Our star undergraduate Rodrigo wondered if a commercial chiral Brønsted acid could be used in our asymmetric photochemistry instead of the optimal BINOL-derived triflimide we originally used. The answer is yes! Rodrigo reports the enantioselective synthesis of δ-truxinates on 2 gram scale in Org Syn. Special thanks to Yu-Che Chang in the Brown group for checking the procedure.
