The synthesis of the natural product 3-epi-casuarine and two tricyclic ether bridged analogues, plus 7-deoxy-3,6-diepi-casuarine, 7-epi-australine, 1-epi-castanospermine and 1,6-diepi-castanospermine is described. The glycosidase inhibitory activities of these compounds, along with that of uniflorine A and other polyhydroxylated pyrrolizidines and indolizidines that we have published before, are reported
天然产物3- Epi- casuarine和两个三环醚桥联的类似物,加上7-脱氧-3,6-di epi - casuarine,7- Epi- australine,1- epi -castanospermine和1,6-di epi的合成-castanospermine被描述。据报道,这些化合物的糖苷酶抑制活性,以及我们以前已发表的单花青素A和其他多羟基化的吡咯并核苷和吲哚并核苷的活性。
