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 azophos

Abstract:

A facile domino reaction of 2-chloroquinoline-3-carbaldehydes in one and two equivalents of isocyanide has been investigated. Three-component reactions of 2chloroquinoline-3-carbaldehydes, isocyanides and amines are also described. In this Pdcatalyzed reaction under controlled conditions, three novel types of quinoline derivatives were formed via amidation, lactamization or carbamate formation along with the formation of C–C, C–N, and C–O bonds in a one-pot procedure.

Abstract:

The synthesis of a novel series of substituted 1,4-dihydropyridines was achieved in aqueous media by base-catalyzed three-component Hantzsch reaction of 2chloroquinoline-3-carbaldehydes, ammonium acetate, and alkyl acteoacetate in good to high yields. Important advantages of this method are easy access to a library of novel quinoline and quinolone derivatives, green reaction conditions with water as solvent, and ease of purification.

Cyclocondensation of 2-chloroquinoline-3-carbaldehydes and 2-thiophenol/2aminophenols led to the formation of benzo[2,3][1,4]thio- or oxazepino[7,6-b]quinolines. Ugi reaction of the latter compound with various carboxylic acids and isocyanides gave novel oxazepino[7,6b]quinoline derivatives. All compounds were evaluated for their antibacterial and anti-fungal activities. Among them, compounds 4a, 4b and 4d showed moderate to good activity.

One pot synthesis of 3,3-dimethyl-3,4-dihydro-2Hdibenzo [b,g][1,8]-naphthyridin-1-one derivatives has been accomplished by three component protocol involving 2-chloroquinoline-3-carbaldehydes, cyclichexanedione and ammonium acetate as a base catalyst. Mild reaction conditions and good yields are obtained by reaction lying in green approach. This route avoids the use of toxic organic solvents, expensive catalysts and anhydrous conditions. The protocol used narrates the interesting development of highly selective methods for the contruction of Ncontaining heterocycle moiety in aqueous medium rea
