meta-Chloroperoxybenzoic acid (m-ClPBA) was shown to be an oxidant for two stereoisomers of menthone oxothiolane. The effect of steric factors on the ability to oxidize the sulfide group was found. Oxidation of (5S,6S,9R)-6-isopropyl-9-methyl-1-oxo-4-thiaspiro[4.5]-decane to the sulfone was prevented by the steric proximity of an isopropyl group to the S atom in the oxothiolane ring.
研究表明,间氯过氧苯甲酸(m-ClPBA)是薄荷酮氧硫杂环戊烷两种立体异构体的氧化剂。研究还发现了立体因素对硫化基团氧化能力的影响。(5S,6S,9R)-6-异丙基-9-甲基-1-氧代-4-噻螺[4.5]-癸烷氧化为砜的过程,因异丙基与氧硫环的 S 原子的立体位相近而被阻止。
