Highly Diastereoselective Approach toward (±)-Tetraponerine T6 and Analogues via the Double Cycloisomerization–Reduction of Bis-alkynylpyrimidines
A new, short, and efficient approach toward tricyclic alkaloids, involving the double cycloisomerization-reduction of bisalkynylpyrimidines 3a–m, has been developed. The requisite bis-alkynylpyrimidines 3a–m were readily prepared via regioselective sequential Sonogashira coupling reactions of dibrom...
