るテトラヒドロフラン誘導体の製造法[Claim 3] The crotyl propargyl ether represented by the formula [4] (2) (wherein G, R2, and Ar have the same meanings as above) is subjected to a thermal ene reaction to produce the compound of the formula (3). ) is stereoselectively derived into a derivative having a tetrahydrofuran ring, and then epoxidized to produce an epoxy compound represented by the formula [5] (4) (wherein G, R2, and Ar have the same meanings as above) When G is a hydrogen atom, it is left as is; when G is a trimethylsilyl group, it is desilylated and then the epoxy ring is opened to form the formula [6] (5) (wherein, R2 and Ar are the same as above) ), the primary alcohol at the 4th position is oxidized to form a carboxylic acid, and the olefin at the 3rd position is further ozonolyzed and reduced, and optionally esterified. Method for producing a tetrahydrofuran derivative represented by the formula [7] (6) (wherein Ar means the same as above)
