carbonyl reduction by sodiumborohydride is described. Unlike the prior bicarbonate-mediated protocol, which proceeds via a salt metathesis reaction, the carbon dioxide-mediated synthesis proceeds via reduction to a monoformatoborohydride intermediate. This has been verified by spectroscopic analysis, and by using aldehydes and ketones as the carbonyl source for the activation of sodiumborohydride. This

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.

organophotosensitizer and photoirradiation was highly effective in accelerating addition reactions. Several nitrones and tertiary amines were successfully utilized to give β-amino hydroxylamines in good yield. Highly regioselective generation of primary α-aminoalkyl radicals based on Lewis's stereoelectronic rule and diastereoselective addition reactions of primary α-aminoalkyl radicals with nitrones were successfully
