“…To make N‐Boc derivatives available by substitution under salt‐free conditions, we probed the new prenucleophile HN(Boc)(CHO), which was expected to be more acidic than HNBoc 2 . This readily available compound14 indeed gave excellent results with respect to yield as well as regio‐and enantioselectivity (Table 2, entries 10–13).…”
Loyal gelling: a C(3) symmetrical L-glutamic acid based gelator was found to instantly form hexagonal nanotubes through anti-solvent gelation in a wide range of mixed solvents at room temperature. Guest molecules, including simple dyes and biological macromolecules, could be entrapped in the nanotubes. This method provides a general and efficient way for the encapsulation of guest compounds in organic nanotubes.

Aryl carbonyl compounds including acetophenones, benzophenones, imides, and benzoic acids are prepared from benzyl substrates using potassium persulfate as oxidant with catalytic pyridine in acetonitrile under mild conditions. Neither transition metals nor halogens are involved in the reactions.
“…As shown, excellent yields were obtained in the reactions of aliphatic nitriles (entries 1-9). In the case of aryl nitriles, the corresponding amides were also produced as side products, therefore the yields decreased in these cases (entries [10][11][12][13][14][15][16]. We decided to conduct the same reaction with other typical Lewis acids such as AlCl 3 , FeCl 3 , ZnCl 2 , NaHSO 4 , etc.…”
A new and convenient method was found for the one-pot synthesis of symmetrical and unsymmetrical linear imides by reaction of aliphatic and aromatic nitriles with acyclic carboxylic anhydrides in the presence of silica sulfuric acid as an active and recyclable reagent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
