An aldehyde compound represented by the formula (1) is reacted with an organometallic compound represented by the formula (2) to give an alcohol compound represented by the formula (3), which is then subjected to deprotection of a hydroxyl group and production of aldehyde by acid hydrolysis.
wherein R1 and R2 are each independently a hydroxyl-protecting group or R1 and R2 in combination show a hydroxyl-protecting group, R3 and R4 are each independently an alkyl group, an aralkyl group, an aryl group or a silyl group or R3 and R4 in combination show a cyclic alkyl group.
化学反应方程式如下:化合物(1)表示的醛类化合物与化合物(2)表示的有机
金属化合物反应,生成化合物(3)表示的
醇类化合物,然后通过酸
水解去保护羟基并生成醛类化合物。其中,R1和R2各自独立地是羟基保护基或R1和R2组合显示出羟基保护基,R3和R4各自独立地是烷基、芳基烷基、芳基或
硅基,或者R3和R4组合显示出环状烷基。
