Cytotoxic neolignans: An SAR study

The cytotoxic effects of different neolignans with the structure 1 were studied. The neolignans, magnolol 1 and honokiol 2 have been reported to inhibit the growth of several tumor cell lines in vitro and in vivo. The chemical structure of magnolol and honokiol consists of biphenyl skeleton with phenolic and allylic functionalities. Analogs of 1 and 2 containing different substitution have been studies for their effect on the growth of Hep-G2 and their structure-activity relationships were reported in this work.

Cu2O: A versatile reagent for base-free direct synthesis of nhc-copper complexes and decoration of 3D-MOF with coordinatively unsaturated NHC-copper species

A new and direct synthetic route for N-heterocyclic carbene (NHC)-copper complexes was disclosed by heating imidazolium halides with Cu2O. The related synthetic procedure was quite simple and the product easily separable from the reaction mixture by simple filtration. Ultimately, this reaction was successfully applied to decorate three-dimensional (3D)-metal organic frameworks (MOFs) with coordinatively unsaturated NHC-copper species

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C27H37ClN2, you can also check out more blogs about250285-32-6

A three dimensional network of iodide ions and iodine molecules in the crystal structure of [Pr(benzo-15-crown-5)2]I21

Black polyhedra of [Pr(benzo-15-crown-5)2]I21 were grown from an ethanol / dichlormethane solution of PrI3, benzo-15-crown-5 and I2. The crystal structure (orthorhombic, P2 1cn, a = 1201.1(1), b = 2168.3(1), c = 2571.1(1) pm, Z = 4) is built up from sandwich like cations [Pr(benzo-15-crown-5)2]3+ and polyiodide anions I213-. This unique polyiodide anion exhibits a complex connection pattern of iodide ions and iodine molecules with variable bond lengths forming a complicated network.

The Structure of [HSi9]3? in the Solid State and Its Unexpected Highly Dynamic Behavior in Solution

We report on the first unambiguous detection of the elusive [HSi9]3? anion in solutions of liquid ammonia by various 29Si and 1H NMR experiments including chemical exchange saturation transfer (CEST). The characteristic multiplicity patterns of both the 29Si and 1H resonances together with CEST and a partially reduced 1H,29Si coupling constant indicate the presence of a highly dynamic Si8 entity and a Si?H moiety with slow proton hopping. Theoretical calculations corroborate both reorganization of Si8 on the picosecond timescale via low vibrational modes and proton hopping. In addition, in a single-crystal X-ray study of (K(DB[18]crown-6))(K([2.2.2]crypt))2[HSi9]?8.5 NH3, the H atom was unequivocally localized at one vertex of the basal square of the monocapped square-antiprismatic cluster. Thus experimental studies and theoretical considerations provide unprecedented insight into both the structure and the dynamic behavior of these cluster anions, which hitherto had been considered to be rigid.

A convenient synthesis of (Z)-3-(alpha-Cyano-alpha-alkoxy-carbonylmethylene)- 2-piperazinones and their derivatives

(Z)-3-(alpha-Cyano-alpha-alkoxycarbonylmethylene)-2-piperazinone derivatives (3) and trans-(Z)-3-(alpha-cyano-alpha-alkoxycarbonylmethylene)octahydro-2(1H)- quinoxalinone derivatives (5) possessing various alkoxycarbonyl groups are prepared directly from the reaction of dialkyl (E)-2,3-dicyanobutenedioates (1) with ethylenediamine (2) and with trans-1,2-diaminocyclohexane (4), respectively. Furthermore, cis-1,2-diaminocycloheptane (6) and meso-2,3- diaminobutane (8) were reacted with the diethyl ester 1b to give cis-(Z)-3- (alpha-cyano-alpha-ethoxycarbonylmethylene)decahydro-2H-cycloheptapyrazin-2-one (7) and cis-(Z)-3-(alpha-cyano-alpha-ethoxycarbonylmethylene)-5,6-dimethyl-2- piperazinone (9), respectively. The structural studies of 3, 5, 7, and 9 were carried out by NMR experiments in some details.

2,2?-biphenols via protecting group-free thermal or microwave-accelerated suzuki-miyaura coupling in water

User-friendly protocols for the protecting group-free synthesis of 2,2?-biphenols via Suzuki-Miyaura coupling of o-halophenols and o-boronophenol are presented. The reactions proceed in water in the presence of simple additives such as K2CO3, KOH, KF, or TBAF and with commercially available Pd/C as precatalyst. Expensive or laboriously synthesized ligands or other additives are not required. In the case of bromophenols, efficient rate acceleration and short reaction times were accomplished by microwave irradiation.

Access to Spiroindolines and Spirodihydrobenzofurans via Pd-Catalyzed Domino Heck Spiroyclization through C-H Activation and Carbene Insertion

A new palladium-catalyzed domino approach for the synthesis of attractive spirocyclic indolines and dihydrobenzofurans was developed. The reaction proceeds through a sequential intramolecular Heck spirocyclization, remote C-H activation, and diazocarbonyl carbene insertion. Various spiroindolines and spirodihydrobenzofurans containing two quartenary carbon stereocenters were readily obtained in good to excellent yields. A preliminary study of asymmetric spirocyclization using chiral monophosphoramidite as a ligand was also conducted, enabling access to highly valuable chiral spiroindolines with up to 80% ee.
