Reaction of 2-acyl-6-methylbenzo[b]furan-3-aceticacids and their derivatives such as amides and esters with hydrazine does not give expected 1-alkyl-5H-benzofuro[2,3-e]diazepin-4-ones ones but results in 2-amino-7-methyl-2H-benzo[4,5]furo[2,3-c]pyridin-3-ones or (3-R-6-methylbenzo[b]furan-2-yl)alkyl ketone azines.
2-酰基-6-甲基苯并[ b ]呋喃-3-乙酸及其衍生物(如酰胺和酯)与肼的反应不能得到预期的1-烷基-5 H-苯并呋喃[2,3 - e ]二氮杂-4 -一个,但生成2-氨基-7-甲基-2 H-苯并[4,5]呋喃[2,3-c]吡啶-3-酮或(3-R-6-甲基苯并[ b ]呋喃- 2-基)烷基酮嗪。
