PROCESS FOR PREPARING A FORMYLALKENYL ALKOXYMETHYL ETHER COMPOUND AND PROCESSES FOR PREPARING CONJUGATED DIENE COMPOUNDS FROM THE SAME

The present invention provide for preparing a formylalkenyl alkoxymethyl ether compound of the following general formula (2): R3CH2OCH2O(CH2)aCH═CHCHO (2), wherein R3 represents a hydrogen atom, an n-alkyl group having 1 to 9 carbon atoms, or a phenyl group; and “a” represents an integer of 1 to 10, the process comprising: hydrolyzing a dialkoxyalkenyl alkoxymethyl ether compound of the following general formula (1): R3CH2OCH2O(CH2)aCH═CHCH(OR1)(OR2) (1), wherein R1 and R2 represent, independently of each other, a monovalent hydrocarbon group having 1 to 15 carbon atoms, or R1 and R2 may form together a divalent hydrocarbon group, R1-R2, having 2 to 10 carbon atoms; and R3 and “a” are as defined above, in the presence of an acid while removing an alcohol compound thus generated to form the formylalkenyl alkoxymethyl ether compound (2).

Synthesis of (3Z,13Z)-3,13-octadecadienyl acetate - Sex pheromone of Synanthedon tenuis-using readily available C11-synthon

Synthesis of (3Z,13Z)-3,13-octadecadienyl acetate has been achieved from the readily available 10-undecen-1-ol using cheaper reagents and less number of steps. In the key step alkylation of an alkyne is performed with solid sodamide giving the product in 50% yield. The method can be easily scaled-up.

SYNTHESIS OF PHEROMONES, IV. CHEMISTRY OF THE WITTIG REACTION, I. EFFECTS OF REACTION CONDITIONS ON THE STEREOSELECTIVITY AND YIELD OF THE WITTIG REACTION

The reactions of nonstabilized triphenylphosphorus ylides with aldehydes have been studied in detail.The stereochemistry and yields of the alkene products are highly dependent upon base used for the generation of the ylide, the solvent and reaction temperature.The synthesis of sex pheromone components by Wittig reaction are also described.
