一般說明
Diethyl chloromalonate (Diethyl α-chloromalonate) is a 2-halo-1,3-dicarbonyl compound.[1] It participates in K2CO3-catalyzed domino reactions (Michael alkylation, Mannich alkylation, and aldol alkylation) of salicylic aldehyde derivatives to afford functionalized 2,3-dihydrobenzofurans.[2] It reacts with Cs2CO3 in the presence of elemental S8 or Sen to afford the corresponding diethyl thioxo- or selenoxomalonates, which can be trapped in situ with various 1,3-dienes.[3]
