reactions using a catalytic amount of tin(II) reagents have been developed. Namely, an aldol type reaction of tin(II) enolate is achieved starting from α,β-unsaturated ketone, aldehyde and ethylthiotrimethylsilane in the presence of a catalytic amount of tin(II) triflate sulfide. Furthermore, the catalytic asymmetric Michael reaction of tin(II) enethiolate is realized just by using a catalytic amount of tin(II)
已经开发出使用催化量的锡(II)试剂的新的碳-碳键形成反应。即,在催化量的三氟甲磺酸锡(II)的存在下,从α,β-不饱和酮,醛和乙基硫代三甲基硅烷开始实现烯醇锡(II)的醇醛型反应。此外,仅通过使用催化量的三氟甲磺酸锡(II)-手性二胺络合物就可以实现烯硫醇锡(II)的催化不对称迈克尔反应。
