Selective One-Step Synthesis of Enantiopure cis-2,5-Disubstituted Pyrrolidines or cis-3,6-Disubstituted Piperidines from the (2R,2'R) (1,2-ethanediyl) Bis-aziridine
New C2 symmetric bis-aziridines efficient synthesis of (2S,5S)-1,6-Di(p-toluenesulfonyloxy)-2,5-hexanediol, and (2S,3E,5S)-1,6-Di(p-toluenesulfonyloxy)-2,5-hexenediol
摘要:
The regioselective tosylation and functionalization of (S,S)-1,2,5,6-hexanetetrol is reported. The reductive aminocyclization of conformationally flexible diazidodiols by PPh(3) leads to C-2 symmetric bis-aziridines and to substituted furans.
