| titleOfInvention | The preparation method of a kind of cis hexahydro furyl also [2,3-b] furan-3-ol |
| abstract | The present invention relates to a kind of novel chirality non-metallic catalyst and catalyze and synthesize cis hexahydro furyl also [2,3-b] method of furan-3-ol, the method is with 2,3-dihydrofuran and glycollic aldehyde dimer are raw material, under the catalysis of chirality non-metallic catalyst oxazaborolidine positive ion, obtain cis hexahydro furyl also [2,3-b] furan-3-ol; The highly selective acylation of this furan alcohol under enzyme catalysis, can be separated further and obtain (3R, 3AS, 6AR)-hexahydro furyl also [2,3-b] furan-3-ol.The inventive method is compared with existing method, more convenient, green, economical. |
