摘要：

An efficient one pot four component strategy has been developed for the synthesis of highly substituted fluoro chromenone derivatives (5a-p) in good yields from beta-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.
