Research speed reading in 2021. An article , which mentions Reference of 42923-79-5, molecular formula is C9H10N2O2. The compound – 7-Nitro-1,2,3,4-tetrahydroisoquinoline played an important role in people’s production and life., Reference of 42923-79-5
1wherein: R1, R2, R3 and R4 independently represent hydrogen, halogen, or alkyl, alkoxy, hydroxy, cyano, optionally substituted amino, nitro, carboxy, alkoxycarbonyl, optionally substituted aminocarbonyl or carbamoyl, L1 and L2 each represents hydrogen or together form ?CH2?CH2?, X1, attached at the 2 or 3 position of the aromatic ring, represents a bond, and in that case X2 represents hydrogen, halogen, or alkyl, alkoxy, hydroxy, nitro, cyano or optionally substituted amino, or X1 and X2, together with two adjacent carbon to which they are bonded in the 2, 3 or 4 position of the aromatic ring, form a (C4-C7)cycloalkyl group, wherein one or two ?CH2? of the cycloalkyl ring are optionally replaced by oxygen or NH, X3 represents hydrogen, halogen, or alkyl, alkoxy, hydroxy, nitro, cyano or optionally substituted amino, G represents a group selected from: 2wherein: the broken lines indicate the optional presence of a double bond, Alk represents linear or branched (C1-C6)alkylene, n is 0 or 1, T3 represents alkyl, optionally substituted aryl, optionally substituted arylalkyl, optionally substituted heteroaryl or optionally substituted heteroarylalkyl, T4 represents alkyl, optionally substituted aryl, optionally substituted arylalkyl, optionally substituted heteroaryl or optionally substituted heteroarylalkyl, and medicinal products containing the same are useful as dual alpha2/5-HT2c antagonist receptors.
