Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 80657-57-4, Name is (S)-Methyl 3-hydroxy-2-methylpropanoate, molecular formula is C5H10O3. In an article, author is Schuster, Christopher H.,once mentioned of 80657-57-4, Formula: C5H10O3.
Prochiral hydrazones undergo efficient and highly selective hydrogenation in the presence of a chiral diphosphine ruthenium catalyst, yielding enantioenriched hydrazine products (up to 99% ee). The mild reaction conditions and broad functional group tolerance of this method allow access to versatile chiral hydrazine building blocks containing aryl bromide, heteroaryl, alkyl, cycloalkyl, and ester substituents. This method was also demonstrated on >150 g scale, providing a valuable hydrazine intermediate en route to an active pharmaceutical ingredient.
