Significance

This is the first example of the reaction between an aldehyde, α-haloaldehyde and a reducing agent, leading to the aldol-type product. The high instability of the β-hydroxyaldehyde products prevents the application of usual low-­valent metal like tin or chromium. The method is convenient and can be easily scaled up.
