Novel compounds which are amide derivatives represented by general formula (I) and medicinal preparations containing the same having an eosinophilic infiltration inhibitory effect based on a potent interferon (.alpha.,.gamma.)-inducing activity and an exellent percutaneous absorbability and being efficacious in treating allergic inflammatory diseases such as atopic dermatitis, various tumors and viral diseases. In said formula, each symbol has the following meaning: R.sub.1 and R.sub.2 : each lower alkyl, etc.; X and Y: independently representing each oxygen, NR.sub.4, CR.sub.5 etc. (wherein R.sub.4 and R.sub.5 independently represent each hydrogen, an aromatic group, etc.); Z: an aromatic ring or heterocycle; R.sub.3 : hydrogen, lower alkoxy, etc.; g, i and k: independently representing each an integer of from 0 to 6; h, i and l: independently representing each an integer of 0 or 1; m: an integer of from 0 to 5; and n: an integer of from 2 to 12.

A novel fluorous‐tagged ammoniaequivalent has been developed. It is based on a nitrogen–oxygen bond, which can be cleaved in a traceless manner by a molybdenum complex or samarium diiodide. The application in the synthesis of ureas, amides, sulfonamides, and carbamates is described. The scope of the fluorous NO linker is exemplified by the synthesis of itopride, a drug used for the treatment of functional
and metal complexation of a new class of perylene bisimides (PBIs) as an integral part of ethylenediaminetetraacetic acid (EDTA) are reported. The simplest representative, namely derivative 1a, was synthesized both by a convergent as well as a direct approach while the elongated derivatives, 1b and 1c, were obtained only via a convergent synthetic pathway. All these new prototypes of water-soluble
A newchemoselective procedure for the reductive transformation of organic azides to the corresponding N-(tert-butoxycarbonyl)amino derivatives using triethylsilane and di-tert-butyl dicarbonate in the presence of a catalytic amount of 20% Degussa is described.

Novel compounds which are amide derivatives represented by general formula (I) and medicinal preparations containing the same having an eosinophilic infiltration inhibitory effect based on a potent interferon (α,γ)-inducing activity and an exellent percutaneous absorbability and being efficacious in treating allergic inflammatory diseases such as atopic dermatitis, various tumors and viral diseases. In said formula, each symbol has the following meaning: R1 and R2: each lower alkyl, etc.; X and Y: independently representing each oxygen, NR4, CR5 etc.(wherein R4 and R5 independently represent each hydrogen, an aromatic group, etc.); Z: an aromatic ring or heterocycle; R3: hydrogen, lower alkoxy, etc.; g, i and k: independently representing each an integer of from 0 to 6; h, i and l: independently representing each an integer of 0 or 1; m: an integer of from 0 to 5; and n: an integer of from 2 to 12.
