PROCESS FOR PRODUCING ALL TRANS-FORM POLYPRENOLS |
摘要 |
<p>An all trans-form polyprenol is obtained by; (A) subjecting a 3,7-dimethyl-6-hydroxy-7-octen-1-ol derivative to five-carbon lengthening reaction m-times which comprises reacting with 2-methyl-3,3-dimethoxy-1-butene and reducing the carbonyl group of the resulting compound, to obtain an allyl alcohol derivative; (B) halogenating the hydroxyl group of the allyl alcohol derivative to convert it to form an allyl halide derivative; (C) allowing the allyl halide derivative to react with a polyisoprenyl sulfone derivative to form a sulfonated polyprenol derivative; and (D) subjecting the sulfonated polyprenol derivative to desulfonylation to obtain the all trans-form polyprenol.</p> |
