General description

2-Chloro-N-methoxy-N-methylacetamide is a Weinreb amide.

Application

2-Chloro-N-methoxy-N-methylacetamide may be used in the preparation of:
  • 2-heptyl-3-hydroxy-4(1H)-quinolone (Pseudomonas quinolone signal or PQS) and structurally related 2-alkyl-4-quinolones having biological activity
  • 2-(benzo[d]thiazol-2-ylsulfonyl)-N-methoxy-N-methylacetamide
  • α-chloro-ketone, starting reagent for the one-pot synthesis of 2-heptyl-3-hydroxyl-4(1H)-quinolone (PQS), signalling molecule in the quorum sensing of Pseudomonas aeruginosa

An optimized procedure for the efficient preparation of 2-heptyl-3-hydroxy-4(1H)-quinolone (Pseudomonas quinolone signal or PQS) and a diverse range of structurally related 2-alkyl-4-quinolones with biological activity is presented. The two-step synthesis begins with the formation of α-chloro ketones by the coupling
