Nelson, Hope; Richard, William; Brown, Hailee; Medlin, Abigail; Light, Christina; Heller, Stephen T. published the artcile< Practical Chemoselective Acylation: Organocatalytic Chemodivergent Esterification and Amidation of Amino Alcohols with N-Carbonylimidazoles>, Recommanded Product: (2-Aminophenyl)methanol, the main research area is alc carbonylimidazole diazabicycloundecene catalyst chemoselective esterification; carboxylic ester preparation; carbonylimidazole aniline pyridinium chloride catalyst chemoselective amidation; aryl amide preparation; amidation; carbonylimidazoles; chemoselectivity; esterification; organocatalysis.
Here, the N-carbonylimidazoles enable catalytic chemodivergent aniline or alc. acylation in the presence of pyridinium ions or 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), was reported. Both acylation reactions display high and broad chemoselectivity for the target group. Unprecedented levels of chemoselectivity were observed in the DBU-catalyzed esterification: A single esterification product was obtained from a mol. containing primary aniline, alc., phenol, secondary amide, and N-H indole groups. These acylation reactions are highly practical as they involve only readily available, inexpensive, and relatively safe reagents; can be performed on a multigram scale; and can be used on carboxylic acids directly by in situ formation of the acylimidazole electrophile.
