Boron trifluoride promoted aldol reaction of silyl ketene acetals with the intermediate generated by the DIBALH reduction of carboxylic acid esters
摘要:
The intermediate generated by the DIBALH reduction of carboxylic acid esters undergoes a boron trifluoride promoted aldol reaction with silyl ketene acetals to afford the corresponding beta-hydroxy carboxylic acids esters in good yield.
