Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 922-67-8, Name is Methyl propiolate, molecular formula is , belongs to thiazolidines compound. In a document, author is Sadou, Nadia, SDS of cas: 922-67-8.
Acid-Catalyzed Synthesis of Thiazolidin-4-ones
A two-steps synthesis of thiazolidin-4-ones, from -tetralone 6 or thiochroman-4-one 7, catalyzed by acids is described. The reactions of -tetralone 6 or thiochroman-4-one 7, with substituted thiosemicarbazides, under AcOH or heteropolyacid (HPAs) catalysis afford thiosemicarbazones 8 and 9 in excellent yields. Condensations of the previous compounds 8 and 9 with -bromoester, under sulfuric acid or heteropolyacid catalysis, yield the corresponding thiazolidin-4-ones 10 and 11.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 922-67-8, in my other articles. SDS of cas: 922-67-8.
