Ruthenium-mediated isomerization and ring-closing metathesis: Versatile syntheses of 6-, 7- and 8-membered benzo-fused heterocycles

摘要

Ruthenium-mediated isomerization and ring-closing metathesis (RCM) were the key steps used to convert a simple substrate, 2-allyl-3-isopropoxy-4-methoxybenzaldehyde, into a variety of 6-, 7- and 8-membered nitrogen- and oxygen-containing benzo-fused heterocycles. [References: 32]
