DTBB-catalyzed lithiation of bis(chloromethyl) sulfone (1) and sulfoxide (3) in the presence of different carbonyl compounds [t-BuCHO, c-C 6 H 1 1 CHO, PhCHO, Me 2 CO, Et 2 CO, n-Pr 2 CO, (CH 2 ) 4 CO, (CH 2 ) 5 CO, (c-C 3 H 5 ) 2 CO, PhCOMe, norbonan2-one] in THF at -90 °C, followed by hydrolysis with water at the same temperature led to the formation of the corresponding dihydroxy sulfones (2) or sulfoxides
在不同的羰基化合物 [t-BuCHO, cC 6 H 1 1 CHO, PhCHO, Me 2 CO, Et 2 CO, n- 存在下,双(氯甲基)砜 (1) 和亚砜 (3) 的 DTBB 催化锂化Pr 2 CO, (CH 2 ) 4 CO, (CH 2 ) 5 CO, (cC 3 H 5 ) 2 CO, PhCOMe, norbonan2-one] 在 THF 中 -90 °C,然后在相同温度下用水水解导致形成相应的二羟基砜(2)或亚砜(4)。这两个系列的代表性化合物已通过 X 射线晶体学进行了分析。
