| titleOfInvention | Method for constructing sterides-6beta, 7beta-methylene structure by cascade reaction |
| abstract | The invention discloses a method for constructing a sterides-6beta, 7beta-methylene structure by a cascade reaction, which comprises the following step that: a 3beta-R3O-5alpha-hydroxy-6beta, 7beta-sterides compound is prepared by the cyclomethylenation reaction of a 3beta-R3O-7alpha-R7-5appha, 6alpha-epoxy-sterides compound serving as a raw material and a methylenation reagent under the complexing action of an inorganic metal salt or an organic metal compound and the initiation action of an initiator. The method has the advantages of readily available materials, fewer reaction steps, simplicity of operation, high stereoselectivity for constructing the 6beta, 7beta-methylene structure unit and high yield of target compounds, and suitability for industrial production. |
