Substituted benzyl ethers are easily cleaved by their treatment with an excess of dimethyldioxirane, the corresponding alcohols are obtained in high yields.
通过用过量的二甲基二环氧乙烷处理可以容易地裂解取代的苄基醚,从而以高收率获得了相应的醇。
Stereoselective Photochemical Cyclization of 3-<i>O</i>-Benzyl-6-deoxy-1,2-<i>O</i>-isopropylidene-α-D-<i>xylo</i>-hexofuranos-5-ulose Derivatives
Photoirradiation of a solution of 3-O-benzyl-6-deoxy-1,2-O-isopropylidene-α-d-xylo-hexofuranos-5-ulose in benzene for 92 h gave (6S)-3,6-anhydro-1,2-O-isopropylidene-5-c-methyl-6-c-phenyl-α-d-gluco- and -β-l-idofuranose in 54% and 11% yield, respectively. Related photocyclizations and solvent effects in the reactions were also described.
