Abstract
AbstractFluorene and fluorenone are privileged structures with extensive utility in both materials science and drug discovery. Here, we describe syntheses of those moieties through isocyanide-based multicomponent reactions (IMCRs) and the incorporation of the products in diverse and complex derivatives that can be further utilized. We performed six different IMCRs, based on the dual functionality of 9-isocyano-9H-fluorene, and we describe 23 unprecedented adducts.

Abstract
An appropriate and efficient Q-tube-assisted palladium-catalyzed strategy for the synthesis of novel, unparalleled diaza-dibenzo[a,e]azulene and diaza-benzo[a]fluorene derivatives has been sophisticated, which includes oxygen and AcOH-induced oxidative C(sp3)-C(sp2) cross-dehydrogenative coupling reactions of 1-amino-2-imino-4-arylpyridine-3-carbonitriles with benzocyclic ketones such as benzosuberone, tetralone, thiochromone, and chromone, respectively. This Q-tube gas purging kit assisted-protocol features safe due to easy pressing and sealing, a wide substrate scope, easy workup and purifying phases, and the use of O2 as a benign oxidant, in addition to being scalable and having a high atom economy. The suggested mechanistic pathway includes a formal dehydrative step followed by palladium AcOH-induced CH(sp3)-CH(sp2) oxidative cross-coupling. In this study, X-ray crystallographic analysis has been used to authenticate the targeted products.

Abstract
BACKGROUND Recently tetrahydrobenzo[b]thiazole derivatives acquired a special attention due to their wide range of pharmacological activities especially the therapeutic activities. Through the market it was found that many pharmacological drugs containing the thiazole nucleus were known. OBJECTIVE This work aimed to synthesize target molecules not only possess anti-tumor activities but also kinase inhibitors. The target molecules were obtained starting from the arylhydrazonocyclohexan-1,3-dione followed by their heterocyclization reactions to produce anticancer target molecules. METHODS The arylhydrazone derivatives 3a-c underwent different heterocyclization reactions to produce thiophene, thiazole, pyrazole and 1,2,4-triazine derivatives. The anti-proliferative activity of twenty six compounds among the synthesized compounds toward the six cancer cell lines namely A549, H460, HT-29, MKN-45, U87MG, and SMMC-7721 was studied. RESULTS Anti-proliferative evaluations, tyrosine and Pim-1 kinase inhibitions were perform for most of the synthesized compounds where the varieties of substituent through the aryl ring and the thiophene moiety afforded compounds with high activities. CONCLUSION The compounds with high anti-proliferative activity towards the cancer cell lines showed that compounds 3b, 3c, 5e, 5f, 8c, 9c, 11c, 12c, 14e, 14f and 16c were the most cytotoxic compounds. Further tests of the latter compounds toward the five tyrosine kinases c-Kit, Flt-3, VEGFR-2, EGFR, and PDGFR and Pim-1 kinase showed that compounds 3c, 5e, 5f, 8c, 9c, 12c, 14e, 14f and 16c were the most potent of the tested compounds toward the five tyrosine kinases and compounds 6d, 11a, 20b and 21e were of the highest inhibitions towards Pim-1 kinase. Pan Assay Interference Compounds (PAINS) for the most cytotoxic compounds showed zero PAINS alert and can be used as lead compounds.

Abstract
A simple and efficient three-component reaction is reported between 2,3-dihydro-7-hydroxythiazolo[3,2-a]pyrimidin-5-one, dimedone and aromatic aldehydes for synthesis of biologically important novel heterocycles containing thiazolo[3,2-a]pyrimidine and chromene as biologically active moieties. The SO3H-functionalised halogen-free ionic liquid [MIM(CH2)4SO3H][HSO4-] is found to be an environmentally benign catalyst for this reaction without using any solvent. This SO3H-functionalised ionic liquid could be recovered and used at least four times without considerable reduction in activity. Good functional group tolerance, broad scope of usable substrates and good to excellent yields of products are the other prominent features of the present synthetic protocol.

Abstract
The molecular mechanism of the three-component reaction of triphenylphosphine, dialkyl acetylene dicarboxylate, and 2-acetylbutyrolactone to synthesize the stabilized phosphorus ylide and 1,3-butadiene derivative via the intramolecular Wittig reaction has been investigated using the density functional theory method at the B3LYP/6-31G level of theory. Two possible reaction pathways have been characterized in detail to form the cyclobutene intermediate and in the next step; the cyclobutene intermediate undergoes the conrotatory ring-opening reaction to produce the 1,3-butadiene derivative along two possible pathways. The calculated results indicate that two pathways (pathways II and II-a) are the most energy favorable among all of the pathways, so they occur more than do the others. Moreover, the phosphorus ylide is more stable than the corresponding 1,3-butadiene, demonstrating that the intramolecular Wittig reaction could not easily occur at room temperature, which is in agreement with the experimental results.

Abstract

Abstract
A highly convergent and regioselective heteroannulation protocol for the synthesis of hitherto unreported highly substituted 2-amino-4-(aryl/alkyl)-5-(aroyl/heteroaroyl)-3-(cyano/carboalkoxy)-6-methylthio-4H-thiopyran derivatives has been developed. This one-pot three-component domino coupling of β-oxodithioesters, aldehydes, and malononitrile/ethyl or methyl cyanoacetate is promoted by 4-dimethylamino pyridine (DMAP) in solvent (dichloromethane (DCM)) as well as under solvent-free conditions. Systematic optimization of reaction parameters identified that the three-component coupling (3CC) protocol is tolerant to a wide array of functionality providing densely functionalized 4H-thiopyrans in excellent yields. The merit of this cascade Knoevenagel condensation/Michael addition/cyclization sequence is highlighted by its high atom-economy, excellent yields, and efficiency of producing three new bonds (two C-C and one C-S) and one stereocenter in a single operation.

Abstract
A protocol has been developed for the efficient synthesis of structurally diverse 3,4-dihydropyridin-2(1H)-ones and 3,4-dihydro-2H-pyrans via four-component reactions of arylamines, acetylenedicarboxylate, aromatic aldehydes and cyclic 1,3-diketones. The selective formation of the very different pyridinone or pyran derivatives depends on the structure of cyclic 1,3-diketone. The key steps are proposed to involve Michael addition of the enamino ester formed in situ from the reaction of arylamine with dimethyl acetylenedicarboxylate to arylidine cyclic 1,3-diketones.
