Abstract
NEW MATERIAL:A compound expressed by formulaI(R1 is H, lower alkyl, etc.; R2 is H or halogen; R3 and R4 are H or with the carbon atoms to which they are linked may form an epoxy ring; R5 is H, OH, etc.; R6 is H or lower alkyl; R7 is lower alkyl; however, R2, R5 and R6 are not H when R1 is H or lower alkyl and R3 and R4 with the carbon atoms to which are they are linked represent an epoxy ring).
EXAMPLE: 4-Bromo-3,4-epoxy-2-methoxy-5-oxo-tetrahydropyran.
USE: A germicide and insecticide capable of exhibiting the activity against bacteria, molds and injurious insects.
PROCESS: A pyran derivative expressed by formula II is reacted with an epoxidizing agent, e.g. peracetic acid or pertrifluoroacetic acid, in the presence of a basic compound, e.g sodium hydroxide or potassium hydroxide, in a solvent, e.g. ether or alcohol, at -30W+40°C for 2W6hr to give the compound expressed by formulaI(R3 and R4 with the carbon atoms to which they are linked form an epoxy ring; R5 is H).
