A robust and green protocol for the reduction of functionalized nitroarenes to the corresponding primary amines has been developed. It relies on inexpensive zinc dust in water containing nanomicelles derived from the commercially available designer surfactant TPGS-750-M. This mild process takes place at room temperature and tolerates a wide range of functionalities. Highly selective reductions can
Several new pyridazino[1',6':1,2]pyrido[3,4-b]indol-5-inium derivatives were synthesised from beta-carboline derivatives and their cytotoxic activity and effect on the cell cycle were evaluated against L1210 cancer cells.

The present invention relates to β-carboline, dihydro-β-carboline and tetrahydro-β-carboline alkaloid derivatives (I) and a method for preparing same and the use in the aspects of preventing and treating plant viruses, fungicides and insecticides. For the meaning of each group in formula (I) see the description. The β-carboline, dihydro-β-carboline and tetrahydro-β-carboline alkaloid derivatives of the present invention show a particularly ourstanding anti-plant virus activity, and also have fungicidal and insecticidal activities.

Nitration of commercial full aromatic β-carboline alkaloids nor-harmane (1), harmane (2), harmine (3), harmol (4), and the 7-acetylated derivative of harmol (5) is described. Advantages and disadvantages of different nitration reagents which involve acidic conditions (HNO3/H+) and neutral conditions (Cu(NO3)2; ceric ammonium nitrate) are discussed. A complete 1H and 13C-nmr characterization including
商用全芳香族β咔啉生物碱的硝化也不-harmane(1),harmane(2),去氢(3),harmol(4),和7-乙酰化衍生物harmol(的5)进行说明。讨论了涉及酸性条件(HNO 3 / H +)和中性条件(Cu(NO 3)2;硝酸硝酸铵)的不同硝化试剂的优缺点。完整的1 H和13给出了C-nmr表征,包括ms以及在中性和酸性介质中的uv吸收光谱。随函附上了详细的ei-ms和ld-tof-ms研究,因为硝基-β-咔啉构成了β-咔啉样生色团的新家族,并有可能在uv-maldi-tof-ms中用作基质。
