The C-arylation can be extended to α-arylation of nitroesters and tolerates other easily arylated functional groups, such as phenols and aliphatic alcohols. Kathlyn A. Parker, Mark W. Ledeboer, Jeremy D. Pettigrew. For the purposes of extensive biological studies, a versatile approach to the synthesis of the AAs and their major metabolites was devised based primarily on a Suzuki-Miyaura coupling reaction. endobj parts.

Clicking on the donut icon will load a page at altmetric.com with additional details about the score and the social media presence for the given article. The oxidation of oximes to nitroalkanes is achieved by employing an Mo(VI) oxodiperoxo complex as oxidant in acetonitrile. There are two key steps in the formation of the nitrile oxide: the removal of the OH proton by base and the loss of chloride. 4 0 obj 19 0 obj Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals.
