Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 23190-16-1, Name is (1R,2S)-(?)-2-Amino-1,2-diphenylethanol, Quality Control of: (1R,2S)-(?)-2-Amino-1,2-diphenylethanol.
The Preparation of (1alpha,3beta)-3-Hydroxycholestane-4,6-diene- 1,25-diol Diacetate from a 5,7-Diene Precursor: A New Method for the Synthesis of Heteroannular Dienes
Starting from the 7alpha-bromide 5a, a regioselective synthesis of (1alpha,3beta)-3-hydroxycholestane-4,6-diene-1,25-diol diacetate (2) is described. The preparative removal of contaminating 5,7-diene 9 was accomplished by the formation of the corresponding Diels-Alder adduct 11. Acetylation of the diacetate 2 followed by acid-catalyzed elimination and rearrangement yielded styrene 13.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Quality Control of: (1R,2S)-(?)-2-Amino-1,2-diphenylethanol. In my other articles, you can also check out more blogs about 23190-16-1
