| 摘 要： | A highly-efficient preparative procedure for ( R, S )- and ( S, S)-pyrroHdine-2-carboxyHc acid 3,5-dioxa-4-boracyclohepta[2, 1-α ; 3,4-α′] dlnaphthalen-4-yl esters [ namely ( R, S )-BNBAP and (S, S )-BNBAP] is described and the crystal structure of (R, S )-BNBAP was obtained. The data indicate that ( R, S )-BNBAP is a spirocyclic inner borate salt with almost normal te-trahedral configuration. This structural form may be the basic reason for their high chemical, optical and thermodynamic sta-bility.

| Abstract: | A highly‐efficient preparative procedure for (R, S) and (S, S)‐pyrrolidine‐2‐carboxylic acid 3,5‐dioxa‐4‐boracyclohepta[2, 1‐a; 3, 4‐a] dinaphthalen‐4‐yl esters [namely (R, S)‐BNBAP and (S, S)‐BNBAP] is described and the crystal structure of (R, S)‐BNBAP was obtained. The data indicate that (R, S)‐ BNBAP is a spirocyclic inner borate salt with almost normal tetrahedral configuration. This structural form may be the basic reason for their high chemical, optical and thermodynamic stability. |
