A novel and facile methodol. for the synthesis of sulfonated benzo[b]oxepinones I (R = H, F, Br; R1 = H, MeO; R2 = Ph, 3-methoxyphenyl, 2-thienyl, etc.; Ar = Ph, 4-methylphenyl, 4-bromophenyl, etc.) and chromane derivatives II (R3 = H, MeO, F, Cl, Br; R4 = H, MeO; R3R4 = -CH=CH-CH=CH-; R5 = Ph, 2-fluorophenyl, 4-methylphenyl; Ar1 = Ph, 2-fluorophenyl, biphenyl-4-yl, etc.) was reported by the reaction of propargyl chalcones 3-R-4-R1-6-OCH2CCHC6H2C(O)CH=CHR2/3-R3-4-R4-6-OCH2CCHC6H2CH=CHC(O)R5 with arylsulfonyl chlorides Ar/Ar1SO2Cl via radical cascade annulation/sulfonation under laboratory conditions. Readily available propargyl chalcones, commercialized arylsulfonyl chlorides, and simple reaction conditions make this six(seven)-membered oxygen-containing heterocycles’ synthetic strategy more attractive and with significant application values. In addition to this study using Thiophene-2-sulfonyl chloride, there are many other studies that have used Thiophene-2-sulfonyl chloride(cas: 16629-19-9Application In Synthesis of Thiophene-2-sulfonyl chloride) was used in this study.
Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides. Sulfonyl chlorides are reactive sulfonic acid derivatives similar in properties and reactivity to acid chlorides of carboxylates. The sulfonic acid group, however, is a highly hindered molecule, containing a tetrahedral configuration of substituents. Application In Synthesis of Thiophene-2-sulfonyl chloride
