Synthesis of (22R)- and (22S)-27-norspirosolane alkaloids from tigogenin, epismilagenin, and smilagenin is described. The alkaloids were prepared from readily available dinorcholanic lactones via their reaction with 4-chlorobutyllithium followed by substitution of chloride with azide and reductive N-cyclization under the Staudinger conditions. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Category: iodides-buliding-blocks).
1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.Category: iodides-buliding-blocks
