The first stereoselective synthesis of sphaeric acid is described. The key step of this synthesis is an efficient ester enolate conjugate addition onto alkylidene bis-sulfoxides with good to high diastereoselectivity. Formation of sphaeric acid allowed the determination of its absolute configuration as 2R.3R.
描述了球形酸的第一次立体选择性合成。该合成的关键步骤是将有效的酯烯醇化物共轭加成到亚烷基双亚砜上,并具有良好到高的非对映选择性。球形酸的形成允许确定其绝对构型为 2R.3R。
