Abstract

Abstract In order to reveal the reactivities of furopyridines, we undertook bromination and nitration of four furopyridines (1, 2, 3 and 4) whose chemical properties had been almost unknown. Bromination of 1, 2, 3 and 4 gave the corresponding trans-2, 3-dibromo-2, 3- dihydro derivatives 6, 8, 10 and 12, respectively, which were converted to 3- bromofuropyridines 7, 9, 11 and 13 by treatment with sodium hydroxide in aqueous ...
