Efficient alkylsulfanyl (SMe, SEt and SCH2Ph) and sulfanyl (SH) migration in the stereospecific synthesis of substituted tetrahydrofurans
摘要:
Treatment of a series of 4-RS-1,3-diols (R=Me, Et, Bn and H) with TsOH in CH2Cl2 gives substituted tetrahydrofurans. We discuss the scope of this reaction using structural variation of the migrating (RS) substitutent All reactions proceeed in high yield and give synthetically useful products.
