| titleOfInvention | Preparation of 2-oxa-bicyclo(3.3.0)octane compounds and their derivatives |
| abstract | The invention relates to a process for the preparation of valuable intermediates for 2-oxabicyclo [3.3.0] octane derivatives of the general formula which are pharmacologically active substances: wherein R, to R 3 and R s are organic radicals and R 2 and R 3 are also hydrogen and R 4 is an acyl radical or a silyl group bearing three organic radicals, by reacting a compound of the formula wherein R, 4 is a lower alkyl radical or a phenyl radical with a compound of the formula where R, 5 represents a trimethylsilyl or a lower alkanoyl group, in an inert solvent in the presence of one or more Lewis acids at temperatures between -80 ° C and + 60 ° C and the products available thereafter. |
