Pinacol homocoupling of (S)-2-[N-(benzyloxycarbonyl)amino] aldehydes by [V2Cl3(THF)6]2[Zn2Cl6]. Synthesis of C2-symmetric (1S,2R,3R,4S)-1,4-diamino 2,3-diols
摘要:
Six (S)-2-[N-(benzyloxycarbonyl)amino] aldehydes 3a-f were homocoupled by [V2Cl3(THF)6]2[Zn2Cl6] (1) to give C2-symmetric (1S,2R,3R,4S)-1,4-bis[N-(benzyloxycarbonyl)amino] 2,3-diols 4a-f in good yield. High-yield conversions of the diols to bisoxazolidinones (sodium hydride, tetrahydrofuran) and to the deprotected (1S,2R,3R,4S)-1,4-diamino 2,3-diol dihydrochloride salts (10% Pd/C, formic acid, HCl in ether) were performed.
