Heterocyclic synthesis by C-C bond formation. Tetrahydrofuran and tetrahydropyran synthesis via oxonium ion-mediated cyclisation reactions

Dimethyl(methylthio)sulfonium tetrafluoroborate triggers ionisation and cyclisation of hemithioacetals 3 to give tetrahydrofurans 8-11 in good yields and stereoselectivities. The homologous sulfone analogues 17 give tetrahydropyrans on treatment with ethy

A novel synthesis of α-(phenylthio)aldehydes

Addition of methoxy(phenylthio)methyllithium to ketones, followed by rearrangement of the adducts, provides a new method for the preparation of α-(phenylthio)aldehydes.The rearrangement is stereospecific.
