CATALYTIC USE OF TIN(II) REAGENTS IN ORGANIC SYNTHESIS

Article abstract of DOI:10.1016/0040-4020(89)80028-6

New carbon-carbon bond forming 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) triflate-chiral diamine complex.
