This work presents a palladium(II)-catalyzed mono-selective C(sp3)-H arylation of pivalic acid for rapid construction of an important library of 3-aryl-2,2-dimethylpropanoic acids, especially ortho-substituted-aryl compounds The strategy greatly streamlines access to a series of trimethyl-lock-type triggers – arylated gem-di-Me carboxylic acids bearing ortho-activatable substituents, which was used as a self-immolative spacer for selective chem. release initiated under specific conditions. Flexible transformation and derivatization of these activatable carboxylic triggers were also showcased. The results came from multiple reactions, including the reaction of ((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol(cas: 20880-92-6HPLC of Formula: 20880-92-6)
((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol(cas: 20880-92-6) is a useful reactant for examining the effectiveness of sulfamate and sulfamide groups for the inhibition of carbonic anhydrase-II (CA-II). And it is used as chiral auxiliaries in Michael and Aldol addition reactions.HPLC of Formula: 20880-92-6
