Abstract
The phosphorus atom in hexamethyl phosphorus triamide 5 attacks the carbonyl function in
2-chloroquinoline-3-carbaldehyde 4a to give the bis-quinolinyl ethanone product 6. On the other hand,
quinoline ring-attack proceeds by the same phosphorus reagent upon reaction with 2-chloroquinoline-
3-aldoxime 4b yielding phosphonate 7. Meanwhile, the reaction of the tris-aminophosphine reagent 5
with 2-chloroquinoline- 3-(p-chlorophenyl)imine 4c affords the respective α-aminophosphonate 8.
Moreover, the attack by phosphine 5 on 2-chloroquinoline-3-imines 4d and 4e produces the respective
cyclic azophosphole derivatives 9a and 9b. [(2-chloroquinolin-3-yl)methylidene]propane dinitrile 4f
reacts with phosphine 5 to yield [(2-chloroquinolinen-3-yl) 2,2-dicyanoethyl]tetramethylphosphonic
diamide 10. Structural elucidations for the new products were based on compatible analytical and spectroscopic
data. Moreover, the structures assigned for compounds 7 and 9a were unambiguously confirmed
by X-ray crystallographic measurements. Biological evaluations indicated that compounds 4a,c
exhibit antibacterial potency against Gram-positive bacteria and 4a,c and 9a show activity against
Candida albicans strain.
