| titleOfInvention |
Bicyclic tetrahydrofuran lactone derivatives and process for the preparation thereof |
| abstract |
The present invention relates to bicyclic tetrahydrofuran lactone derivatives of Formula (1) and a preparation method thereof, and particularly it relates to a process of preparing compounds of Formula (1) by performing an intramolecular cyclization of tetrahydrofuran-allenic acid derivatives in the presence of a phenyl halide, a palladium catalyst and a base: n nwherein n is 1 or 2, and R is phenyl optionally substituted with C 1 –C 6 alkyl, C 1 –C 6 alkoxy, hydroxyl or C 1 –C 6 hydroxyalkyl group. |
