Synthesis of functionalized benzothiophenes and dibenzothiophenes by twofold Heck and subsequent 6π-electrocyclization reactions of 2,3-dibromothiophenes and 2,3-dibromobenzothiophenes
Benzothiophenes and dibenzothiophenes were prepared by twofoldHeckreactions of 2,3-dibromothiophene and 2,3-dibromobenzothiophene, respectively, and subsequent thermal 6π-electrocyclization. The Heckreaction of 2,3-dibromothiophene and 2,3-dibromobenzothiophene with 1 equiv of alkenes proceeded with different regioselectivities and afforded 2-alkenylthiophenes and 3-alkenylbenzothiophenes.
Efficient Synthesis of Functionalized 2,3-Di(alkenyl)benzothiophenes and Dibenzothiophenes Based on the First Heck Reactions of 2,3-Di- and 2,3,6-Tribromobenzothiophene
Alkenyl-substituted benzothiophenes were prepared by the first Heck reactions of 2,3-di- and 2,3,6-tribromobenzothiophene. Functionalized dibenzothiophenes were prepared based on domino ‘twofold Heck-6Ï-electrocyclization’ reactions.
