In a method for producing a de-dimethoxybenzylated compound by removing a dimethoxybenzyl group from a compound containing a dimethoxybenzyl group bonded to a nitrogen atom in the presence of an acid, the de-dimethoxybenzylated compound is obtained by removing the dimethoxybenzyl group without forming a poorly soluble product resulting from the removed dimethoxybenzyl group. The de-dimethoxybenzylation reaction is carried out in the presence of triphenylphosphine or diethylthiourea.
A novel series of benzoylsulfonamide derivatives were synthesized and biologically evaluated. Among them, 4-(biphenyl-4-ylmethylsulfanylmethyl)-N-(hexane-1-sulfonyl)benzamide (compound 18K) was identified as a proteintyrosinephosphatase 1B (PTP1B) inhibitor with potent and selective inhibitory activity against PTP1B (IC50=0.25 µM). Compound 18K functioned as a non-competitive inhibitor and bound

Fluazaindolizine is a new highly effective and selective product for the control of plant parasitic nematodes. Specificity for nematodes coupled with absence of activity against the target sites of commercial nematicides suggests that fluazaindolizine has a novel mode of action. The discovery, structure-activity development and biological properties for this new class of nematicides are presented.
