Next, we tested more bulky‐bulky ketones, namely substrates having an increased steric hindrance on the other side of the carbonyl moiety. Substrates with a hydroxyl or a chloro‐ substituent on the methyl group led to conversion of 97 % or >99 % (15 a and 16 a, Table 1,...
to address this issue. Baijiu samples subjected to various aging conditions were analyzed using direct GC-MS and HS-GC-MS, and the obtained data was processed by this approach. The results demonstrate significantly superior performance compared to other methods, including PLSR and Gradient Boosting....

For example, in the case of oxidations, only a very limited set of substrates can be utilized to generate a ketone, most commonly the oxidation of an alcohol, although ketones can certainly be accessed through other types of reactions as well. This leads to the relatively higher accuracies ...
The second announcement is that in our recording today, I chat a little bit about perfect keto exogenous ketones. Just wanted to let you guys know if you want to give their product a try, you can use the coupon code HEALTHFUL. That’s all in caps, no spaces. It’s H-E-A-L-T-H...
Totally 75 volatile compounds were identified by SDE/GC-MS analysis and classified by kinds of substance in all set of treatments, including 24 alcohols, 16 aldehydes, 7 ketones, 2 esters, 12 hydrocarbons, 1 acid, 2 phenolic compounds, 3 oxygen compounds, 7 nitrogenous compounds and 1 sulfur...

Despite the wide range of conceptually different syntheses, only few methods for introducing chirality into pyridine side chains have been described: Enantioselective reduction of pyridine carbonyl compounds, the addition of lithiated pyridine derivatives to chiral ketones or the resolution of racemates ...
an aromatic ketone include acetophenone, benzophenone, benzoin ethyl ether, benzyl methyl ketal, benzyl ethyl ketal, benzoin isobutyl ketone, hydroxy dimethyl phenyl ketone, 1-hydroxycyclohexyl phenyl ketone, 2,2-diethoxy acetophenone, and Michlers' ketone Thus, various aromatic ketones can be used...
