✦ Synopsis
The reaction of Reformatsky reagents with α-amidoalkylphenyl sulfones proceeds in dichloromethane at room temperature leading to the synthesis of the corresponding β-amino esters in good yields. The procedure presents syn stereoselectivity and can be also extended to Reformatsky reagents based on γ-bromocrotonates.
