Multi-membered N-heterocycles

Use of N—N Bond Stereodynamics in Ring-Closing Metathesis to Form MediRings and Macrocycles. — A hydrazine-based ring-closing metathesis
11- 166 um-Sized
platform utilizes the conformational constraint of N-substituted diacylhydrazines and
is effective for a variety of dienes and enynes affording functionalized 8- to 14-membered rings. The new strategy is applied for rapid access to a macrocyclic amide (V)
from a bicyclic hydrazine derivative (IV). — (KIM, Y. J.; LEE*, D.; Org. Lett. 6
