Thiazolobenzyne: a versatile intermediate for multisubstituted benzothiazoles
Thiazolobenzyne, which is a benzyne species fused with a thiazole ring, was efficiently generated via an iodine-magnesium exchange reaction of an ortho -iodoaryl triflate-type precursor using a trimethylsilylmethyl Grignard reagent as an activator. A wide range of arynophiles reacted efficiently wit...

Zusammenfassung: | Thiazolobenzyne, which is a benzyne species fused with a thiazole ring, was efficiently generated
via
an iodine-magnesium exchange reaction of an
ortho
-iodoaryl triflate-type precursor using a trimethylsilylmethyl Grignard reagent as an activator. A wide range of arynophiles reacted efficiently with the thiazolobenzynes generated by this method to afford various multisubstituted benzothiazoles.
Thiazolobenzynes were efficiently generated from
ortho
-iodoaryl triflate-type precursors, which enabled facile synthesis of various multisubstituted benzothiazoles. |
