Of the various 6-substituted-5-methoxy-δ-lactams 6 were synthesized from α-sulfonyl acetamide 9 in 4 steps in good yield. The key glutarimides 7 were obtained via facile 3+3 annulation. The method featured regioselective introduction of C-6 substituents in glutarimides 7 . Synthesis of tribenzyl lactam 8 and the formal synthesis of (±)-homopumiliotoxin 223G were also reported.
