Easily obtained 1-methyl-2-(1′-hydroxyalkyl)-1H-imidazoles (4) were found to be a new type of masked form for carbonyl group which could survive under various severe conditions. The corresponding carbonyl compounds (3) were easily reproduced by quarternization of the imidazole (4) with CH3I followed by aqueous basic treatment. 2-Acyl-1H-imidazoles (5) were convertible to aldehydes or ketones (3) by
容易获得的1-甲基-2-(1'-羟烷基)-1H-咪唑(4)被发现是一种新型的羰基掩蔽形式,可以在各种恶劣条件下生存。通过用CH 3 I对咪唑(4)进行季铵化,然后进行碱性水溶液处理,可以容易地复制相应的羰基化合物(3)。通过使用本发明的方法,可以将2-酰基-1H-咪唑(5)转化为醛或酮(3)。
