چکیده
2-(Bromomethyl)-1-sulfonylaziridines were converted into novel 3-sulfonamido-2,3,4,5-tetrahydro-1,5-benzothiazepines upon treatment with 2-aminothiophenol in THF in the presence of K2CO3. Starting from 3-substituted 2-(sulfonyloxymethyl)aziridines, a regio- and stereocontrolled synthesis of trans-2-phenyl- and trans-4-(phenyl or propyl)-3-sulfonamido-2,3,4,5-tetrahydro-1,5-benzothiazepines was developed in good yields via two different reaction pathways, depending on the nature of the sulfonyloxy group.

1-arylmethyl-2-(bromomethyl)aziridines were transformed into the corresponding 2(cyanomethyl)aziridines and 2-(2-cyanoethyl)aziridines upon treatment with potassium cyanide in DMSO and α-lithiated trimethylsilylacetonitrile in THF, respectively. Further elaboration of 1-arylmethyl-2-(cyanomethyl)aziridines afforded 4-amino-2-butenenitriles, 3,4diaminobutanenitriles and 2-aminocyclopropanecarbon...

متن کاملSynthesis of 5-hydroxy-2,3,4,5-tetrahydro-[1H]-2-benzazepin-4-ones: selective antagonists of muscarinic (M3) receptors.
Two approaches to tetrahydro-[1H]-2-benzazepin-4-ones of interest as potentially selective, muscarinic (M(3)) receptor antagonists have been developed. Base promoted addition of 2-(tert-butoxycarbonylamino)methyl-1,3-dithiane with 2-(tert-butyldimethylsiloxymethyl)benzyl chloride gave the corresponding 2,2-dialkylated 1,3-dithiane which was taken through to the dithiane derivative of the parent...
متن کاملStereoselective Lewis acid mediated (3+2) cycloadditions of N-H- and N-sulfonylaziridines with heterocumulenes.
Alkyl and aryl isothiocyanates and carbodiimides are effective substrates in (3+2) cycloadditions with N-sulfonyl-2-substituted aziridines and 2-phenylaziridine for the synthesis of iminothiazolidines and iminoimidazolidines. Additionally, the stereoselective (3+2) cycloaddition of N-H- and N-sulfonylaziridines with isothiocyanates can be accomplished, allowing for the synthesis of highly enant...
متن کاملFused 1,5-benzothiazepines from o-aminothiophenol and its derivatives as versatile synthons.
This review describes the reactions of o-aminothiophenol and its derivatives as building blocks for the synthesis of poly-functionalised 1,5-benzothiazepines with pharmacological interest. Annelated 1,5-benzothiazepines were prepared by acyclocondensation reaction of o-aminothiophenol and its derivatives with carbonyl and other functionalities. In case ofcarbonyl function this reaction takes pl...
