Regioselective synthesis of functionalized 3,5-diketoesters and 2,4-diketosulfones by uncatalyzed condensation of 1-methoxy-1,3-bis(trimethylsilyloxy)-1,3-butadienes with α,β-unsaturated acid chlorides and sulfonyl chlorides

of 1-methoxy-1,3-bis(trimethylsilyloxy)-1,3-butadienes with alpha,beta-unsaturated and functionalized acid chlorides afforded a variety of 3,5-diketoesters which are not readily available by other methods. The reaction of 1-methoxy-1,3-bis(trimethylsilyloxy)-1,3-butadiene with sulfonyl chlorides allows a direct synthesis of 2,4-diketosulfones.
1-甲氧基-1,3-双(三甲基甲硅烷氧基)-1,3-丁二烯与α,β-不饱和和官能化的酰氯的反应提供了各种3,5-二酮酸酯,这些是其他方法不易获得的。1-甲氧基-1,3-双(三甲基甲硅烷氧基)-1,3-丁二烯与磺酰氯的反应可直接合成2,4-二酮砜。
