ASYMMETRIC SYNTHESIS OF FURO(3,4-C)PYRIDINE DERIVATIVES |
| 摘要 |
The invention relates to a method for the preparation of a non-racemic furo [3,4-c] pyridine derivatives of the formula I <IMAGE> I wherein R1, R2 and R3 stand for various substitutents, comprising adding a concentrated strong acid to a solution of a non-racemic compound of the formula II <IMAGE> II in an amount sufficient to catalyze a deprotection/cyclodehydration. These compounds are known antihypertensives. |
