摘要
The synthesis of a novel enantiopure gamma/delta-amino acid having the 3-aza-6,8-dioxabicyclo[3.2.1]octane structure was realized by the combination of tartaric acid derivatives and alpha-amino acetophenone followed by a trans-acetalisation process. This amino acid, which has a rigid skeleton and carries substituents at the 3, 5 and 7 positions of the scaffold, could find different applications in organic and peptidomimetic synthesis. Two different synthetic strategies were studied, one of them allowing the multigram scale preparation of the amino acid. (C) 2002 Elsevier Science Ltd. All rights reserved.
