Synthesis, structural characterization and anti-carcinogenic activity of new cyclotriphosphazenes containing dioxybiphenyl and chalcone groups

2,2-Dichloro-4,4,6,6-bis[spiro(2?,2?-dioxy-1?,1?-biphenylyl]cyclotriphosphazene (2) was synthesized from hexachlorocyclotriphosphazene (HCCP) and 2,2?-dihydroxybiphenyl. The mixed substituent chalcone/dioxybiphenyl cyclophosphazenes (2a-h) were obtained from the reactions of (2) with hydroxy chalcone compounds in K2CO3/acetone system. The chalcone-cyclophosphazene compounds were characterized by elemental analysis, FT-IR, 1H, 13C, 31P NMR techniques. In vitro anti-carcinogenic activities of all compounds were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Anti-carcinogenic activity of the compounds (2a-h) against androgen-dependent (LNCaP) and independent (PC-3) human prostate cancer cell lines were investigated. Our results indicate that the chalcone-phosphazene compounds (2a-h) have anti-carcinogenic activity on PC-3 and LNCaP cell lines (p < 0.05). The effective dose of the compounds was determined as 100 muM. Do you like my blog? If you like, you can also browse other articles about this kind. Formula: C12H10O2.

Iridium-catalyzed N-alkylation of diamines with glycerol

N-alkylation of 1,2-diaminocyclohexanes with glycerol in water, catalyzed by [Cp*IrCl2]2, gives a mixture of 2-methyldecahydroquinoxaline and 2-(1-hydroxyethyl)-3a,4,5,6,7,7a-hexahydro-1H- benzimidazoles.

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: C6H14N2, you can also check out more blogs about1436-59-5

Bis(amino)allenylidene complexes by displacement of the MeO group in methoxy allenylidene complexes of chromium and tungsten. Synthesis, DFT calculations and solid-state structures of new bis(amino)allenylidene complexes

Pentacarbonyl dimethylamino(methoxy)allenylidene tungsten, [(CO) 5WCCC(OMe)NMe2] (1b), reacts with one equivalent of primary amines, H2NR, by selectively replacing the methoxy group to give dimethylamino(amino)allenylidene complexes, [(CO)5WCCC(NHR) NMe2]. When the amine is used in excess both terminal groups, OMe as well as NMe2, are replaced by the primary amino group giving [(CO)5WCCC(NHR)2 ]. The NHR substituent in these complexes may be modified by deprotonation with LDA followed by alkylation. The replacement of the methoxy group in 1b by a secondary amino group, NR 2, can be achieved by a stepwise process. Addition of Li[NR 2] to the Cgamma atom of 1b affords an alkynyl tungstate. Subsequent OMe- elimination induced by TMS-Cl/SiO 2 yields the allenylidene complexes [(CO)5WCCC(NR 2)NMe2]. When bidentate diamines are used instead of monoamines both substituents, OMe and NMe2, are replaced and allenylidene complexes are formed in which Cgamma constitutes part of a 5-, 6-, or 7-membered heterocycle. The reaction of [(CO) 5CrCCC(OMe)NMe2] (1a) with diethylene triamine affords an allenylidene complex with a heterocyclic endgroup carrying a dangling CH 2CH2NH2 substituent. All reactions follow a strict regioselective attack of the nucleophile at Cgamma and proceed with good to excellent yields. The addition of N-H to the C alphaCbeta bond is not observed. By applying either one of these routes nearly any substitution pattern in bis(amino)allenylidene complex can be realized.

Intramolecular N-H insertion of alpha-diazocarbonyls catalyzed by Cu(acac)2: An efficient route to derivatives of 3-oxoazetidines, 3-oxopyrrolidines and 3-oxopiperidines

Cu(acac)2 was found to be an efficient catalyst for the intramolecular N-H insertion by carbenoids. The competitive intramolecular C-H insertion by carbenoids is not a problem in the diazo decomposition reaction with Cu(acac)2 as catalyst. The reaction provided derivatives of 3-oxoazetidine, 3-oxopyrrolidine and 3-oxopiperidine in moderate to good yields.

Ar-BINMOL-derived salan-Cu(II) complex-catalyzed silyl-reformatsky reaction of aromatic aldehydes

In this work, we have developed a facile protocol with salan-Cu system for the facile and selective synthesis of beta-hydroxyesters via silyl-Reformatsky reaction with -silylester and aldehydes. The screening and optimization of reaction conditions led to the determination of a practical and efficient procedure in which the salan-Cu exhibited promising catalytic activity in dimethylsulfoxide, in which the silyl-Reformatsky reaction of aromatic aldehydes with -trimethylsilylmethylacetate gave the corresponding beta-hydroxyester derivatives in excellent yields (up to 98%) under fluoride-free reaction conditions.

From Concept to Crystals via Prediction: Multi-Component Organic Cage Pots by Social Self-Sorting

We describe the a priori computational prediction and realization of multi-component cage pots, starting with molecular predictions based on candidate precursors through to crystal structure prediction and synthesis using robotic screening. The molecules were formed by the social self-sorting of a tri-topic aldehyde with both a tri-topic amine and di-topic amine, without using orthogonal reactivity or precursors of the same topicity. Crystal structure prediction suggested a rich polymorphic landscape, where there was an overall preference for chiral recognition to form heterochiral rather than homochiral packings, with heterochiral pairs being more likely to pack window-to-window to form two-component capsules. These crystal packing preferences were then observed in experimental crystal structures.
