Synthesis of the Bestmann-Ohira reagent

The conversion of an aldehyde to a terminal alkyne by means of a one-carbon chain extension is a key reaction in organic synthesis. By using dimethyl 1-diazo-2-oxopropylphosphonate, the Bestmann-Ohira reagent, the transformation can be achieved in one pot. A reliable, convenient sequence for the preparation of the Bestmann-Ohira reagent is described. Georg Thieme Verlag Stuttgart.

Insertion reaction of azidosulfonyl azo dye with model alicyclic and heterocyclic compounds

Thermal reactions of 4-(2-hydroxynaphthalen-1-yldiazenyl)benzenesulfonyl azide with cyclohexane, benzene, toluene, anisole, p-xylene, mesitylene, dihydropyran, and pyridine were studied. Structures of the resulting azo dyes were confirmed by FT-IR, UV, 1H and 13C NMR, and mass spectra and elemental analyses, and their solvatochromic properties were examined. Probable mechanisms of nitrene insertion were discussed.

Au-Cavitands: Size governed arene-alkyne cycloisomerization

With an inwardly directed reactive center and a well-defined binding pocket, Au(I) functionalized resorcin[4]arene cavitands have been shown to catalyze molecular transformations. The reactivity profiles that emerge differ from other Au(I) catalysts. The added constraint of a binding pocket gives rise to the possibility that the substrates might have to fit into the resorcinarene pocket; our hypothesis is that substrates that match the available space have different reaction outcomes than those that do not. Herein we report on the intramolecular cyclization of alkyne-aromatic substrates with variable alkynes and aromatic composition. We see that scaffold size most drastically dictates reactivity, especially when the substrate's features are particularly designed. The results of these experiments add to the veritable goldmine of information about the selectivity in catalysis that cavitands offer.

Synthesis of Allylboranes via Cu(I)-Catalyzed B-H Insertion of Vinyldiazoacetates into Phosphine-Borane Adducts

Cu(I) catalysts enable C-B bond formation via direct insertion of vinyldiazoacetates into B-H bonds of borane-phosphine Lewis adducts to form phosphine-protected allylboranes under mild conditions. The resulting allylborane-phosphine Lewis adducts can be used in the diastereoselective allylation of aldehydes directly without the need for removal of the phosphine. The allylation reaction proceeds with high diastereoselectivity and yields 5,6-disubstituted dihydropyranones after treatment with an appropriate acid.

One-pot synthesis of sulfonyl-1H-1,2,3-triazolyl-thiomorpholine 1,1-dioxide derivatives and evaluation of their biological activity

A one-pot procedure for the synthesis of novel 1,2,3-triazole derivatives (5a–5l) in good yields (63 to 77%) using different sulfonic acids and 4-(prop-2-yn-1-yl)thiomorpholine 1,1-dioxide through the in situ generated sulfonyl azides was developed. The structures of the newly synthesized compounds were confirmed by 1H NMR, 13C NMR, mass spectrometry, and elemental analysis. The newly synthesized compounds were screened for in?vitro antibacterial activity and free radical scavenging activity in terms of hydrogen donating or radical scavenging ability by the DPPH method. Among all, the compound N-(4-((4-((1,1-dioxidothiomorpholino) methyl)-1H-1,2,3-triazol-1-yl)sulfonyl)phenyl) acetamide (5l) was found to exhibit potent activity as compared to the standard drugs.

Microchannel synthesis method of aryl sulfonyl azide

The invention discloses a microchannel synthesis method of aryl sulfonyl azide. Sodium azide and water are uniformly stirred and prepared into a material A, aryl sulfonyl chloride and acetone are uniformly stirred and prepared into a material B, and the material A and the material B are continuously fed into a microchannel reactor at the flow rate of 6mL/min-70mL/min and efficiently react to prepare the aryl sulfonyl azide. Compared with the prior art, the microchannel synthesis method has the advantages that process route operation is safe, conversion rate is high, cost is saved, and the yield of the aryl sulfonyl azide is higher than 80%.

Palladium(0)-Catalyzed Carbonylative Synthesis of N-Acylsulfonamides via Regioselective Acylation

N-Acylsulfonamides represent an important bioisostere of carboxylic acids that allow for greater molecular elaboration and enhanced hydrogen bonding capabilities. Herein, we present a mild and convenient palladium(0)-catalyzed synthesis of N-acylsulfonamides via the carbonylative coupling of sulfonyl azides and electron-rich heterocycles. The reaction proceeds via in situ generation of a sulfonyl isocyanate followed by regioselective acylation of an indole or pyrrole nucleophile. This approach has been used to synthesize 34 indole- and pyrrole-substituted N-acylsulfonamides in yields of up to 95%. Importantly, this process is ligand-free and compatible with an ex situ solid CO source and requires only slightly elevated temperatures, making it a highly attractive method for the preparation of this important class of compounds. This study further investigated the possibility of labeling N-acylsulfonamides with carbon-11 to facilitate biological evaluation and in vivo studies with positron emission tomography.
