Paragraph 00296, (2014/05/24)
Compounds having the following formula I: or a stereoisomer or pharmaceutically-acceptable salt thereof, where R1, R2, R3, R4, and R5 are as defined herein, are useful in the modulation of IL-12, IL-23 and/or IFNa, by acting on Tyk-2 to cause signal transduction inhibition.
Nucleophilic photosubstitutions of o-methoxynitrobenzenes

We report a new synthesis of 3-nitroveratrole, based on the directed lithiation of veratrole, and photochemical substitutions of both 3-nitroveratrole and o-nitroanisole with several nucleophiles.Both aromatic substrates undergo photocyanation meta to the nitro group.With hydroxide ion, 3-nitroveratrole reacts meta to the nitro group, but 2-nitroanisole undergoes replacement of either substituent, the proportion of reaction at each site depending upon the OH(-) concentration. 3-Nitroveratrole undergoes an inefficient reaction with butylamine at each methoxy group; this reaction is apparently second order in amine.The reaction between o-nitroanisole and diethylamine results only in photohydrolysis.Keywords: photosubstitution, nucleophilic, 3-nitroveratrole, o-nitroanisole
