Intramolecular 6-exo-dig Post-Ugi Cyclization of N‑Substituted 2‑Alkynamides: Direct Access to Functionalized Morpholinone Glycoconjugates

We herein report a chemo- and regioselective 6-exo-dig catalytic cyclization of Ugi adducts N-substituted 2-alkynamides to access functionalized morpholinone glycoconjugates in the presence of triphenylphosphine. This array allows an interesting multicomponent access to a library of functionalized m...
