An efficient one pot four component strategy has been developed for the synthesis of highly substituted fluoro chromenone derivatives ( 5 a‐p ) in good yields from β ‐aryl thio acetanilide, aldehydes, cyclic 1,3‐diketones and NFSI ( N ‐Fluorobenzenesulfonimide) in presence of water. The fluoro imino chromenone intermediate 6 is isolated under the inert condition in high yield.
