Abstract
NEW MATERIAL:An acetal compound shown by the formula I (R1 is 1W6C alkyl, etc.; R2 is alkyl, alkenyl, etc.; R3 is H, alkyl, etc.; R4 is 1W3C alkyl).
EXAMPLE: 3-Acetyl-1,1-dimethoxy-2-methyl-3-p-toluenesulfonyl-hexa-5-in.
USE: An intermediate for agricultural chemicals, drugs. Also useful as an intermediate for cyclopentenolone, prostaglandin, etc.
PROCESS: A nitro compound shown by the formula II is reacted with a base (e.g., sodium methylate, sodium hydroxide, etc.) and with an acid, e.g., sulfuric acid, etc. in an alcohol shown by the formula R4OH, preferably at -30W30°C for 5minW 10hr, to give a compound shown by the formula I.
