一般描述

Diethyl chloromalonate (Diethyl α-chloromalonate) is a 2-halo-1,3-dicarbonyl compound. It participates in K₂CO₃-catalyzed domino reactions (Michael alkylation, Mannich alkylation, and aldol alkylation) of salicylic aldehyde derivatives to afford functionalized 2,3-dihydrobenzofurans. It reacts with Cs₂CO₃ in the presence of elemental S₈ or Se_n to afford the corresponding diethyl thioxo- or selenoxomalonates, which can be trapped in situ with various 1,3-dienes.
