In 2015,Xue, Xiaochao; Li, Wei; Yin, Zhaojun; Meng, Xiangbao; Li, Zhongjun published 《Concise and direct construction of cis-pyrano[4,3-b]pyran-5-one skeleton from glucal derivatives: synthesis of ent-4-deoxy-2,3-di-epi-dinemasone BC》.Tetrahedron Letters published the findings.COA of Formula: C2H4I2 The information in the text is summarized as follows:
(-)-Dinemasones B and C were isolated from a culture of the endophytic fungus Dinemasporium strigosum and had shown attractive antimicrobial activities in vitro. Described herein is the concise synthesis of their analog, ent-4-deoxy-2,3-di-epi-dinemasone BC, from glucal derivatives, including C-glycoside and 3-deoxy-glucal, and the strategies proceeded in 7 steps in 13% overall yield and in 9 steps in 17% overall yield resp. In the part of experimental materials, we found many familiar compounds, such as 1,2-Diiodoethane(cas: 624-73-7COA of Formula: C2H4I2)
1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.COA of Formula: C2H4I2
