- A set of 27- to 39-membered pyridine macrocycles 2 and 3 has been synthesized by Williamson ether synthesis or ring-closing metathesis. The pyridines are 2,6-disubstituted to allow low endo interactions. In addition to t...
- Asymmetric Synthesis of (-)-Lentiginosine by Double Aza-Michael Reaction
