The invention provides compounds and compositions comprising compounds that modulate histone acyl transferase (HAT). The invention further provides methods for treating neurodegenerative disorders, conditions associated with accumulated amyloid-beta peptide deposits, Tau protein levels, and/or accumulations of alpha-synuclein as well as cancer by administering a compound that modulates HAT to a subject.

Isatoic anhydride derivatives having an N-substituent which includes a quaternary ammonium group are useful for labeling and/or functionalizing a target material and/or for coupling materials together. The isatoic anhydride derivatives of the present disclosure can be advantageously water soluble, easily prepared and purified. Isatoic anhydride derivatives useful in the present disclosure preferably have at least one chemically reactive group or at least one binding group or at least one detectable label. Anthranilate derivatives made from the isatoic anhydrides derivatives or otherwise and kits including the isatoic anhydride derivatives are also disclosed.

The present invention relates to the preparation of cyantraniliprole, comprising the preparation of 8-methyl-2,4-dioxo-1,4-dihydro-2H-benzo[d][1,3]oxazine-6-carbonitrile key intermediate via 2-amino-5-((hydroxyimino)methyl)-3-methylbenzoic acid. Wherein hydroxylamine attacks a benzylic formyl group, to obtain the 2-amino-5-((hydroxyimino)methyl)-3-methylbenzoic acid, that undergoes simultaneously or by consecutive steps dehydrogenation and cyclization to obtain the benzo[d][1,3]oxazine group and the cyano group of the desired product. In addition, an improved method for the synthesis of the benzylic formyl group is also displayed.
