A simple and straightforward method for the synthesis of primary α-ketoamides has been discovered. The reaction represents the first example of benzylimidates directly converting to primary α-ketoamides by using sustainable molecular oxygen as an oxidant. This reaction proceeds in the presence of copper(II) salt via cleavage of benzylic C-H and C-O bonds of the benzylimidates with liberation of alcohols as the only byproduct. A wide substrate scope, operationally mild conditions, the use of single substrates, and a reaction scaled up to grams make this strategy very attractive and practical. Furthermore, mechanistic studies illustrate that the imidate group adjacent to the benzylic position plays crucial role in facilitating this chemical process.

A highly efficient molecular iodine catalyzed oxidative amidation of aryl methyl ketones with formamidine hydrochloride has been developed. This reaction represents a novel strategy for the synthesis of free (N-H) α-ketoamides. Based on the experimental r

Abstract Indolyl-3-carbonylnitriles are compounds with demonstrated utility as intermediates in organic chemistry. However, their synthesis remains a challenge, requiring the use of toxic sources of cyanide, and often proceeding in low yields. Accordingly, presented here is a new synthesis of these versatile reactants, via dehydration of easily accessible α-oxoacetamides in generally high yields under simple reaction conditions.
The first synthesis of [11C]SB-216763, a new potential PET agent for imaging of glycogen synthase kinase-3 (GSK-3)

experimental part, p. 245 - 249 (2011/02/27)
SB-216763 is a novel, potent and selective glycogen synthase kinase-3 (GSK-3) inhibitor with an IC50 value of 34 nM. [11C]SB- 216763 (3-(2,4-dichlorophenyl)-4-(1-[11C]methyl-1H-indol-3-yl)-1H- pyrrole-2,5-dione), a new potential PET agent for imaging of GSK-3, was first designed and synthesized in 20-30% decay corrected radiochemical yield and 370-555 GBq/μmol specific activity at end of bombardment (EOB). The synthetic strategy was to prepare a carbon-11-labeled maleic anhydride intermediate followed by the conversion to maleimide.

(Chemical Equation Presented) Indolylaryl and indolylheteroarylmaleimides, including bisindolylmaleimides, are easily prepared by the reaction of N-methylindole-3-glyoxylamide with methyl aryl acetates in the presence of potassium tert-butoxide in THF.
