S,Sâ²-Diethyl dithiomalonate 1 undergoes concomitant alkylation reaction and Michael addition with Ï-iodo-α,β-unsaturated ketones; the dithiomalonate group present in the cyclization products can be easily reduced by Raney nickel to the ethanol level.
S,Sα-二硫代丙二酸二乙酯 1 与α-碘-α,β-不饱和酮同时发生烷基化反应和迈克尔加成反应;环化产物中存在的二硫代丙二酸基团可以很容易地被雷尼镍还原至乙醇水平。
