A Novel Route to 1-Azaazulenes by the Reaction of b-Amino Enones with Activated Tropones
摘要:
The reaction of beta -amino enones with activated tropones (2-bromo-, 2-chloro-, and 2-tosyloxytropones) underwent an enamine alkylation followed by dehydrating condensation to give 1-azaazulene derivatives in modest yields.
