Quinoline methiodide (1) reacts with ethyl bromocyanoacetate (2a) in the presence of triethylamine to afford ethyl 2-methyl-9-oxo-2,10-diazabenzo[c]tricyclo[4,2,1,07,11]nonane-8-carboxylate (3a) in 24.1% yield. The products of the same type (3b-d and 3f) are obtained from reactions of 1 with bromocyanoacetamide (2b), α-bromophenylacetonitrile (2c), α-bromo-p-nitrophenylacetonitrile (2d), and o-tosylates of benzaldehyde and p-chlorobenzaldehyde cyanohydrins (2e and 2f).
