The Bronsted acid catalyzed formal insertion of an isocyanide into a C-O bond of an acetal is described. A diverse array of acyclic and cyclic acetals can be applied to the catalytic insertion to form α-alkoxy imidates. Functional groups, such as nitro, c
Controllable Intramolecular Unactivated C(sp3)-H Amination and Oxygenation of Carbamates

Dual catalyst-controlled intramolecular unactivated C(sp3)-H amination and oxygenation of carbamates merging visible-light photocatalysis and earth-abundant transition metal catalysis have been reported. Useful amino alcohol and diol derivatives could be selectively obtained from readily available tertiary alcohol derivatives. The possible mechanisms have been proposed via a 1,5-HAT process followed by Lewis acid-controlled cyclization. The nickel and zinc catalysts inhibit the formation of oxygenation and amination products, respectively. An interesting phenomenon of chirality transfer is also observed.

1-Alkoxybenzocyclobutenes undergo ring-opening hydrogenolysis with site-selective cleavage of the sterically hindered C(sp2)-C(sp3) bond on Pd/C.
Almond oxynitrilase-catalyzed transformation of aldehydes is strongly influenced by naphthyl and alkoxy substituents
Roda, Gabriella,Riva, Sergio,Danieli, Bruno
, p. 3939 - 3949 (2007/10/03)
Different α- and β-substituted aldehydes have been submitted to the catalytic action of almond oxynitrilase (PaHNL), in order to explore the influence of a stereocenter already present in the substrate on the selectivity of this enzyme. The results indicate that naphthyl and alkoxy substituents in the α- and also in the β-position to the aldehyde group significantly influence the stereochemical outcome of the PaHNL-catalyzed transformation.
Rearrangement of Carboxylates derived from N-Acetyl-N-nitroso-&α-amino-acids
Chow, Yuan L.,Polo, Joel
, p. 297 - 299 (2007/10/02)
While N-acetyl-N-nitrosophenylalanine thermally decomposes by the known mechanism, its carboxylate anion undergoes facile rearrangements initiated by carboxylate attack in methanol or water to give 2-methoxy- or 2-hydroxy-3-phenylpropanoic acid, respectively.
