An efficient method for the synthesis of [1,4]thiazino[4,3-a]indole derivatives using sodium chlorodifluoroacetate (ClCF2CO2Na) and elemental sulfur as the difluoromethylthiolating reagent system has been developed. Three-component reactions of 2′-aminochalcones, sulfur, and ClCF2CO2Na under basic conditions using TEMPO as the oxidant afforded [1,4]thiazino[4,3-a]indol-10-ones containing a difluoromethyl thioether moiety in good yields. Four bonds including one C-N, two C-S, and one C-C bonds are selectively formed in the sequential transformation process.

In search for the new antimicrobial agents owing to drug resistant bacteria and fungi, a series of rationally designed aza analogs of flavones has been designed and synthesized. The design of the analogs involved incorporation of quinolone nucleus within
Palladium-catalyzed heteroannulation with acetylenic carbinols as synthons-synthesis of quinolines and 2,3-dihydro-4(1H)-quinolones

o-Iodoanilides 4 reacted with terminal acetylenic carbinols 5 under palladium-catalyzed conditions to yield o-substituted anilides 6. Most of the anilides 6 could be cyclized with NaOEt/EtOH to 2-arylquinolines 2. o-Iodoanilines 7 reacted with carbinols 5 leading to 8 which on palladium(II) assisted cyclisation afforded substituted quinolines 2. An excellent synthesis of the alkaloid dubamine (2n) is reported. Also, the anilides 6 on acid-catalyzed rearrangement, deprotection and cyclisation led to the 2-aryl-2, 3-dihydro-4(1H)-quinolones 16.
