Abstract
The title aldehyde is prepared by LiAlH4 reduction of the correspondin g serine derived methyl ester to the alcohol and Swern oxidation of th e latter. The aldehyde is obtained in 94 % yield and 96-98 % enantiome ric purity. This method avoids some problems encountered in the synthe sis of the same aldehyde by direct controlled DIBAL reduction of the e ster.
