摘要:An unsaturated compound of formula R1 ¦ C-OR3 PARALLEL X in which R1 and R3 represent alkyl groups of 1 to 4 carbon atoms and XH is R2 which represents a primary or secondary alkyl group of 1 to 4 carbon atoms, is reacted with an alkanol of formula R4OH, in which R4 represents a normal alkyl group of 1 to 4 carbon atoms, in the presence of, as catalyst, a strong cation exchange resin in the acid form, to produce a ketal of formula R1 ¦OR3 C ANGLE ¦OR4 R2 which may be used in the synthesis of pesticides.

摘要:Substituted olefinic (allyl) benzene compounds which exhibit important antimicrobial (antibacterial and antifungal) activity, compositions and methods of delivery against pathovars and pathogens, and methods of synthesis from commonly available reactants. The antifungal composition active ingredient is one or more 4,5-substituted 2,3-alkylidenedioxy-1-olefinic benzenes of the formula: Formula I where R1 and R2 may be the same or different, and are selected from OH, and C1-C5 alkoxy (-OR) or thioalkyl (-SR) groups. R3 and R4 are selected from H and C1-C5 alkyl, alkenyl and alkynyl groups, and R5 is selected from C3-C7 alkyl, alkenyl and alkynyl groups. The preferred compounds are 4,5-substituted-2,3-methylenedioxy-1-allyl benzenes. Where R1=OCH3, R2=OH, R3 and R4=H and R5=allyl (2',3' propenyl) the compound may be called nor methyl-pseudo-dillapiole. Where R1=R2=OCH3, R3 and R4 are again H, and R5=allyl, the compound may be called pseudo-dillapiole. Compositions including these compounds exhibit antimicrobial activity against a variety of pathogens and pathovars, e.g., Xanthomonas campestris spp. bacteria, antifungal activity against a variety of fungi and bacteria, and are highly specific, e.g., antifungal activity against wheat powdery mildew, but do not affect seed germination or have herbicidal or insecticial activity. Methods and compositions for delivery of these agents against such pathogens, and methods of chemical synthesis of the compounds are disclosed.
