The present invention relates to a new low-molecular spiro, ketone and carboxylic acid compounds and their derivatives having an affinity for (PO3H2)Ser/(PO3H2) Thr-Pro-specific peptidyl-prolyl-cis/trans-isomerases of the parvuline family and which inhibit their enzymatic peptidyl-prolyl-cis/...
We posited that a carboxylic acid could be directly used as a latent electrophile (C-terminus) rather than a nucleophile (O-terminus) in cross-coupling. This could simplify and upgrade ketone synthesis from carboxylic acids and organic halides13. Very recently, our group and Doyle et al. ...
Besides alkyl carboxylic acids, benzylic C(sp 3 )–H also could be functionalized to form 3,4ヾihydroisocoumarin structures in a single step from 2﹎ethyl benzoic acid derivatives. The utility of these protocols was demonstrated in large scale reactions and diversifications of the γ〤(sp 3 ...

The Grignard reaction is a reaction with a carbonyl and an organometallic reagent called the Grignard reagent. Carbonyls are an organic functional group where carbon is double-bonded to oxygen. This includes compounds such as ketones, aldehyde, carboxylic acids, and carboxylic acid derivatives. Organom...
48 Both methods utilize trimethylsilyl chloride (TMS-Cl) at some point during ketone preparation; the former method of Rubottom introduces TMS-Cl once addition of the alkyllithium to the carboxylic acid is complete. This was done in an effort to trap residual methyllithium and allow the use ...
CONSTITUTION:A carboxylic acid is subjected to the catalytic vapor-phase reaction using zirconium oxide as the catalyst at 300-500 deg.C to obtain 1 molecule of the corresponding ketone from 2 molecules of the carboxylic acid. The conversion, selectivity and catalyst life in the above reaction ...
and it's the subject of another set of videos that can be found in your carboxylic acid derivatives chapter. But for right now, all I'm trying to say is that acid chlorides and esters when reacted with organometallics are going to react twice instead of reacting o...
