- METHOD FOR PRODUCING 3,7-DIMETHYL-7-OCTENOL AND METHOD FOR PRODUCING 3,7-DIMETHYL-7-OCTENYL CARBOXYLATE COMPOUND
-
Methods selectively and efficiently produce 3,7-dimethyl-7-octenol and a carboxylic acid ester thereof. More specifically, a method produces 3,7-dimethyl-7-octenol, including steps of: subjecting a 3-methyl-3-butenyl nucleophilic reagent (2) and a 1,3-dihalo-2-methylpropane compound (3) to a coupling reaction to obtain a 2,6-dimethyl-6-heptenyl halide compound (4); converting the compound (4) into a 2,6-dimethyl-6-heptenyl nucleophilic reagent (5); and subjecting the nucleophilic reagent (5) to an addition reaction with at least one electrophilic reagent selected from the group made of formaldehyde, paraformaldehyde and 1,3,5-trioxane, followed by a hydrolysis reaction to obtain 3,7-dimethyl-7-octenol (6); and the other method.

- Universal approach to the synthesis of juvenoid hydroprene and methoprene from 4-methyltetrahydropyran
-
A universal approach to the synthesis of juvenoid hydroprene and methoprene was developed on the basis of monoalkylation of acetoacetate by 1-acetoxy-5-bromo-3-methylpentane, the product of acidic decyclization of 4-methyltetrahydropyran.
