Enantioselective synthesis of 2-(3′-alkyl-2′-carboxy cyclopropyl)glycines
摘要:
New conformationally restricted glutamate analogues 2-(3'-alkyl-2'-carboxycyclopropyl)glycines (1a-c and 2a-c) were enantioselectively prepared by the addition-elimination reaction of the chiral lithium bislactim ether anion of 3 to racemic 4-alkyl-4-bromobut-2-enoates, (C) 1999 Elsevier Science Ltd, All rights reserved.
