摘要
以三氯氧磷为环化试剂,回流状态下,N-(4,5-二溴-2-吡咯甲酰基)-β-丙氨酸经分子内酰化环化反应,合成了生物活性化合物2,3-dibromoaldisin。其结构经1HNMR1、3CNMR、IR、FABMS和元素分析确证。测定了该化合物对α-葡萄糖苷酶的抑制作用。
2, 3-Dibremoaldisin (2, 3-dibremo-6, 7-dihydro-H1, 5H-pyrrulo [ 2, 3-c ] azepine-4, 8-dione ) was synthesized by cyclization of 3-[(4,5-dibremopyrrole-2- carbonyl ) amino ] proplonlc acid under reflux using phosphorus oxychlofide as the cyclization rea-gent. Its structure was characterized by ^1HNMR, ^13CNMR, FABMS, IR and elementary analysis. The effect of title compound on inhibition of a-glucosidase was also studied.
