Abstract
Lithiation of the dihydropyrrole (I) with butyllithium (II) and subsequent addition of triethylborane (III) yield the lithium borate (IV) which is alkylated with the halides (V), producing the boranes (VI).
ChemInform Abstract
Lithiation of the dihydropyrrole (I) with butyllithium (II) and subsequent addition of triethylborane (III) yield the lithium borate (IV) which is alkylated with the halides (V), producing the boranes (VI). In the presence of copper(I) cyanide, alkylation leads to the elimination of the boron moiety, yielding the alkyldihydropyrroles (VII). Similarly, (IV) is coupled with the cyclohexenyliodonium tetrafluoroborate (IX) to give the cyclohexenyldihydropyrrole (X).
