　　The investigation of the chemistry of indoles has been, and continues to be, one of the most active areas of heterocyclic chemistry.[1] In particular, β-indolylketones have received much attention as important building blocks for the synthesis of many natural products and other biologically active compounds.[2] In continuation of our work in the synthesis of indole derivates,[3] we describe the remarkable catalytic of PTSA as a cheaper catalyst in ultrasound-accelerated Michael reaction of indole with α, β-unsaturated ketones (2), which provide one of the most efficient routes to the synthesis of β-indolyketones. In all cases, the substitution on the indole nucleus occurred exclusively at the 3-position, and N-alkylation products have not been observed. In addition, the structure of 3a was further confirmed by single crystal X-ray crystallography.……

Indole fragment is featured widely in a wide variety of pharmacologically and biologically active compounds.[1] The 3,3-bis(3-indolyl)oxindole has been shown to possess antibiotic activities against Escherichia coli, Bacillus subtilis and Staphylococcus aureus. [2] As a continue of our work on the synthesis of indole derivates such as bis(indolyl)methanes,[3]we describe an ultrasound-accelerated reaction of isatin 1 with indoles 2 using a catalytic amount of ceric ammonium nitrate (CAN), which provides an efficient route to the synthesis of 3,3-di(1H-indol-3-yl)indolin-2-ones.……

In recent years, much attention has been directed towards the syntheses of 1,4-dihydropyridyl compounds due to the fact that 1,4-dihydropyridyl compounds possess a variety of biological activities.[1] In view of the importance of polyhydroquinoline derivatives, many classical methods for the synthesis of polyhydroquinoline derivatives were reported[2] by conventional heating and refluxing approaches in the presence of organic solvent. These methods, however, involve long reaction time, harsh reaction conditions, the use of a large quantity of organic solvent and unsatisfactory yields. Therefore,improvements in such syntheses have been sought continuously.……

The reactions of [(h5-C5Me5)Mo(StBu)3] with equimolar FeBr3 in THF afforded a neutral tetranuclear cluster [(h5-C5Me5)2Mo2Fe2S4Br2] 1. The structure of 1 was determined by single-crystal X-ray diffraction analysis. 1 crystallizes in the monoclinic space group P21/n (No. 14) with a = 9.691(2), b = 15.204(2), c = 18.850(2) ? b = 96.44(1), V = 2759.8(7) ?, Z = 4, Mr = 862.08, Dc = 2.075 g/cm3, F(000) = 1680, m (MoKa) = 51.31 cm-1 and T = 296.2 K. With the use of 3667 observed reflections (I > 3.0s(I)), the structure was refined to R = 0.041 and Rw = 0.051. 1 is composed of a distorted Mo2Fe2S4 cubane core with two Br atoms and two h5-C5Me5 groups coordinating at the Fe and Mo sites, respectively. The lengths of MoMo and FeFe bonds are 2.826 and 2.773 ? respectively the mean length of MoFe bond is 2.751 ?

The title compound （C19H23NO3） was synthesized by the one-pot reaction ofp-methoxybenzaldehyde, Meldrum＇s acid, dimedone and CH3NH3Cl （NaOAc） in ethanol under microwave irradiation without catalyst and its crystal structure was determined by single-crystal X-ray diffraction. The crystal is of monoclinic, space group P21/c with a = 8.7462（10）, b = 17.7367（19）, c = 11.5959（14） A, β = 110.981（3）°, V= 1679.6（3） A^3, Z = 4, Dc = 1.239 g/cm^3,μ（MoKa） = 0.083 mm^-1, F（000） = 672 and Mr = 313.38. The structure was refined to R = 0.0530 and wR = 0.1216. X-ray analysis reveals that the dihedral angle between plane 1 （N（1）, C（1）, C（2）, C（3）） and plane 2 （C（1）, C（2）, C（6）, C（7）, C（9）） is 3.64°, andt hat between plane 2 and plane 3 （C（11）～C（16）） is 85.33°.
