A stereoselective thiocyanate conjugate addition to electron deficient alkynes and concomitant cyclization to N, S-heterocycles

A regio- and stereoselective thiocyanate addition to ynones is achieved using KSCN in AcOH at 70 degrees C. The reaction is extendable to ynals, ynesulfones, ynoic acids and ynoates. Adducts from ynones were readily transformed into thiazine-2-thione derivatives under slightly modified reaction conditions. In contrast, thiocyanated adducts from ynamides underwent an in situ decyanative amido cyclization towards isothiazolones. None of these events needed any transition metal or catalyst, attaining a high synthetic value.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 82911-69-1. The above is the message from the blog manager. Quality Control of N-(9-Fluorenylmethoxycarbonyloxy)succinimide.

Herein, an effectual, quick and novel method is described for the synthesis of new triazolo[1,5-a]pyrimidine, triazolo[5,1-b][1,3] thiazine and pyrazolo[1,5-a]pyrimidine derivatives. This series of fused six-member rings to triazole and pyrazole was prepared via the catalyst-free reaction of dialkyl acetylenedicarboxylates and 3-substituted 1H-1,2,4-triazole or 3-amino-1H-pyrazole-4-carbonitrile. The structures of the prepared products were deduced from their Fourier-transform infrared, elemental analysis and proton and carbon-13 nuclear magnetic resonance spectral data. Graphical abstract A novel and green method is described for the synthesis of new triazolo[1,5-a]pyrimidine, triazolo[5,1-b][1,3] thiazine and pyrazolo[1,5-a]pyrimidine derivatives. [GRAPHICS] .

Widely Electronically Tunable 2,6-Disubstituted Dithieno[1,4]thiazines-Electron-Rich Fluorophores Up to Intense NIR Emission

2,6-Difunctionalized dithieno[1,4]thiazines were efficiently synthesized by (pseudo)five- or (pseudo)three-component one-pot processes based on lithiation-electrophilic trapping sequences. As supported by structure-property relationships, the thiophene anellation mode predominantly controls the photophysical and electrochemical properties and the electronic structures (as obtained by DFT calculations). From molecular geometries and redox potentials to fluorescence quantum yields in solution, the interaction of the dithieno[1,4]thiazine-core with the substituents causes striking differences within the series of regioisomers. Most interestingly, strong acceptors introduced inanti-antidithieno[1,4]thiazines nearly induce a planarization of the ground-state geometry and a highly intense NIR fluorescence (phi(F)=0.52), whereas an equally substitutedsyn-syndithieno[1,4]thiazine exhibits a much stronger folded molecular structure and fluoresces poorly (phi(F)=0.01). In essence, electrochemical and photophysical properties of dithieno[1,4]thiazines can be tuned widely and outscore the compared phenothiazine with cathodically shifted oxidation potentials and redshifted and more intense absorption bands.

One-pot cis-selective route to sugar-fused thiazines via a masking-unmasking strategy in basic ionic liquid

A novel sequential Knoevenagel condensation, thia-Michael, and amino/mercaptoacetylative ring transformation reaction cascade for cis-selective synthesis of sugar-fused 1,3-thiazine is reported. The expeditious one-pot multicomponent annulation was performed using masked amino acid viz. 2-phenyl-1,3-oxazol-5-one or masked mercaptoacid viz. 2-methyl-2-phenyl-1,3-oxathiolan-5-one, D-xylose/D-glucose, and N-aryldithiocarbamic acid in ionic liquid [bmim] OH. The acetophenone obtained as a by-product and [bmim] OH itself could be easily recycled for further use without loss of efficiency. The envisaged method is operationally simple, high yielding, and excellent diastereoselective in favor of the cis-isomer of fused thiazines.

Phenyliodine(III) Diacetate/I-2-Mediated Domino Approach for Pyrrolo[1,4]Thiazines and 1,4-Thiazines by a One-Pot Morin Rearrangement of N,S-Acetals

An efficient domino transformation using a phenyliodine(III) diacetate (PIDA)/I-2 combination towards Morin 1,4-thiazine compounds has been developed starting from N,S-acetals. The latter leads to one-step regioselective methylene insertion without the need for traditional sulfoxide intermediates in good yields. The reaction involves easily accessible N,S-acetals obtained from cost-effective basic ketones and cysteamine as starting materials. This process ultimately leads to 1,4-thiazines related to natural product and fused derivatives necessary for further QSAR study.
