Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. SDS of cas: 21461-84-7. Introducing a new discovery about 21461-84-7, Name is (S)-( )-5-Oxo-2-tetrahydrofurancarboxylic Acid
The syntheses of six enantioenriched analogs representing cyclic forms of acetylcholine are reported. (S)- and (R)-N-(2-chloroethyl)-3-acetoxypiperidine and (R,R)-, (R,S)-, (S,R)-, and (S,S)-N-(2-chloropropyl)-3-acetoxypiperidine have been synthesized from (R)- or (S)-3-hydroxypiperidine in five steps. (R)- and (S)-3-hydroxypiperidine were accessed via parallel stereospecific routes from d- and l-glutamic acid, and through fractional recrystallization of diastereomeric tartranilic acid salts. (S)-N-(2-Chloroethyl)-3-acetoxypiperidine was reacted with silver perchlorate to form a spirocyclic aziridinium analog of acetylcholine as evidenced by a characteristic 1H NMR shift for the aziridinium methylene groups.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of (S)-( )-5-Oxo-2-tetrahydrofurancarboxylic Acid, you can also check out more blogs about21461-84-7
