Abstract
NEW MATERIAL:A compound shown by the formula (R1 is lower alkyl; R2 is H or lower alkyl).
EXAMPLE: 4-Methoxy-1,3-dioxane-5-carbonitrile.
USE: An intermediate for synthesizing vitamin B1.
PROCESS: A 3-alkoxy-2-propenenitrile (e.g., 3-methoxy-2-propenenitrile, etc.) shown by the formula R1O-CH=CH-CN is reacted with an aldehyde (e.g., formaldehyde, acetaldehyde, etc.) shown by the formula R2CHO in the presence of an acid catalyst (e.g., AlCl3, H2SO4, etc.) in a solvent such as dioxane, benzene, etc. at -20W300°C, to give a compound shown by the formula.
