The Mitsunobu reaction of ortho-ethers of secondary benzylic alcohols. Concise enantioselective synthesis of a key intermediate of the novel β-adrenergic receptor antagonist MY336-a

日期:1996.7
Chiral secondarybenzylicalcohols bearing an ortho-alkoxy substituent suffer ring-assisted racemization during the Mitsunobureaction; however, their congeners bearing also a 3-substituent undergo virtually complete Mitsunobu inversion. A conciseenantioselectivesynthesis of a keyintermediate of the β-adrenergicreceptorantagonistMY336-a was achieved exploiting this observation.

Assembly of the azepine ring of xantheno[9,1-cd]azepines by electrophilic cyclization of sulfonamide acetals provides access to clavizepine analogues in the form of 2,12b-dihydroor 4-hydroxy-2,3,4,12b-tetrahydro-1H-xantheno[9,1-cd] azepines, in the latter case producing the trans derivative stereoselectively. Binding assays for clavizepine and analogues at adrenergic, dopaminergic, and serotonergic receptors are reported.

Moreover, by solving the crystal structures of these new salts, we suggest that the solvation structures around K+ ions in these crystals may provide hints of the solvation structures in solvent-lean concentrated electrolytes. In this work, we have demonstrated this concept by grafting ether solvent moieties onto trifluoromethylsulfonamide to form potassium asymmetric salts. The solubility in dimethylethane
