Disclosed is a novel process for the reduction of nitro groups to amino derivatives, based on the use of trichlorosilane and an organic base, which is efficient from the chemical standpoint and of wide general applicability.ベナグリア,マウリツィオボンシニョーリ,マルティナ...
or a salt thereof, wherein R1, R2, and R3 have the above given meaning, to a compound of formula 5, or a salt thereof whereas compounds of formula 1 are obtained by reduction of the nitro group to an amine group, mesylation of this amine group and cleavage of the protecting group...
The present invention discloses catalytic process of preparing amine through reducing nitro compound with hydrogen. The process adopts nitro compound as main material, inorganic palladium salt microcapsule as catalyst in the amount of 0.01-2 %, and n-hexane, tetrahydrofuran, benzene, toluene or ...

Alternatively, the aldehyde can be condensed first with the amine under conditions where water is excluded to form the imine. Then the imine is treated with a cyanide carrier optionally in the presence of a suitable catalyst when required. ...
2,4-Diaminopyrimidines (e.g., brodimoprim, tetroxoprim, trimethoprim), nitrofurans (e.g., furaltadone, furazolium chloride, nifuradene, nifuratel, nifurfoline, nifurpirinol, nifurprazine, nifurtoinol, nitrofurantoin), quinolones and analogs (e.g., cinoxacin, ciprofloxacin, clinafloxacin,...
METHODS FOR REDUCING SWEAT AND/OR BODY ODOR, USING PHOSPHONATE COMPOUNDS WITH AMINE AND/OR HYDROXYL GROUPS The present invention relates to methods for reducing body perspiration and/or for reducing the body odor resulting from perspiration. According to these methods, an antiperspirant cosmetic agent...
A method of reducing an aromatic nitro (-NO) group to the corresponding amine (-NH) group by treatment with iron or zinc metal and a halogen-containing aliphatic carboxylic acid provides amines in good yield and free from unwanted anilides.GOURLEY, ROBERT NICHOLAS...
