Abstract
NEW MATERIAL:An aldehyde compound of formula I [R1 is II (R4 is H, alkyl, or halogen), pyridyl, etc.; R2 is alkyl, alkenyl, alkynyl, etc.; R3 is H, alkyl, phenyl, etc.].
EXAMPLE: 2-Methyl-3-phenylthio-3-acetyl-5-hexen-1-al.
USE: An intermediate of pesticides and medicines. Cyclopentenolone derivatives which are important intermediates of pesticides can be derived from the title compound, easily, in high yield. Also useful as an intermediate of prostaglandin.
PROCESS: The compound I is prepared by reacting a nitro compound of formula III (novel compound) with a base such as KOH, NaOH, etc., and reacting the product with an acid such as sulfuric acid in the presence of water, pref. at -30W +30°C.
