Novel heterocycles. 6. The condensation of ethyl o‐fluorobenzoyl acetate with cyclic imino ethers

Abstract
The reaction between ethyl o‐fluorobenzoylacetate and cyclic imino ethers is described. The products, the corresponding 1,2‐fused quinolines (13a‐17a), were isolated in good yields. In one instance the uncyclized condensation intermediate 18 was isolated and characterized.
