摘要
A novel pyrrolo-benzoxaborole,6-(pyrrol-1-yl)-1,3-dihydro-1-hydroxy-2,1-benzoxaborole,was synthesized with 27%overall yield over six steps from 2-bromo-1-methyl-4-nitrobenzene as starting material.Its derivatization was achieved via Friedel-Crafts reaction catalyzed by anhydrous stannic chloride with various acyl chlorides giving 3-acyl-1-phenylpyrroles as the main products.
