Abstract

NEW MATERIAL:A pyran derivative of formula I (R1,4 are H or lower alkyl; R2 is lower alkoxy, lower alkenyl, cycloalkyl or nitro-lower alkyl; R3 is H or halogen; R5 is H, lower alkyl, or lower alkanoyl which may have a halogen atom as substitution group).
EXAMPLE: 6-Cyclohexyl-2-hydroxy-5-oxo-5,6-dihydro-2H-pyran.
USE: Microbicide, insecticide and miticide, especially useful as an agricultural and horticultural microbicide.
PROCESS: The objective compound I is prepared by hydrolyzing the compound III which can be prepared by the electrolytic oxidation of a furfuryl alcohol derivative II (R6 is lower alkenyl, cycloalkyl, etc.; R7 is lower alkyl) is an alcohol, in the presence of a catalyst such as ammonium bromide, under the following electrolytic conditions: electrical voltage; 1W30V, current density; 0.001W0.1A/cm, and quantity of electricity; about 2F/mol.
