New research progress on 166591-85-1 in 2021. SDS of cas: 166591-85-1, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 166591-85-1, molcular formula is C15H19NO4, introducing its new discovery.
The hydrogenation of beta-keto esters containing a furan unit at the conjugated position to the beta-carbonyl group was carried out over a chiral heterogeneous catalyst, tartaric acid-modified Raney nickel. The hydrogenation first proceeds at the carbonyl to give optically active alcohols, but a simple substrate undergoes further hydrogenation of the furan part to produce a diastereomeric mixture of alcohols having a tetrahydrofuran moiety. This over-reduction was efficiently suppressed by substitutions of a substituent at the furan part. The optical yield at the hydroxy group is in the range of 40-90%.
We are continuing to develop the new Research Structures and WebCSD systems in response to feedback from you, our user community, so we would love to hear what you think about the enhanced search functionality and any suggestions you might have about 166591-85-1
