Reaction of (S)-2-oxo-4-methyl-4-phenyl-1,3,2-dioxathiolane with triethylaluminum selectively took place at the tertiary carbinol center to give (R)-2-methyl-2-phenyl-1-butanol. Enhanced stereoselectivity was obtained in a nonpolar solvent. Similarly, a series of (S)-4,4-disubstituted-1,3,2-dioxathiolanes reacted with trimethylaluminum to afford the corresponding (R)-2-alkyl-2-phenyl-1-propanols in
(S)-2-氧代-4-甲基-4-苯基-1,3,2-二氧杂硫杂环戊烷与三乙基铝的反应在叔甲醇中心选择性地发生,得到(R)-2-甲基-2-苯基-1 -丁醇。在非极性溶剂中获得增强的立体选择性。类似地,一系列(S)-4,4-二取代-1,3,2-二氧杂硫杂环戊烷与三甲基铝反应以良好的产率得到相应的(R)-2-烷基-2-苯基-1-丙醇。
