Total synthesis of pteridic acids A and B.
The total synthesis of pteridic acids A and B is reported. The convergent asymmetric synthesis involved the use of a diastereoselective ethyl ketone aldol reaction followed by an efficient spiroketalization and provided pteridic acids A and B in 2.9% and 2.8% overall yield, respectively.
