REFERENCES

• This hindered acetal, in conjunction with an alcohol, converts carboxylic acids to esters of that alcohol: Angew. Chem. Int. Ed., 3, 62 (1964); Helv. Chim. Acta, 48, 1746 (1965). For application to the lactonization of ω-hydroxyacids, giving lactones of up to 16-membered rings, in modest yield, see: Angew. Chem. Int. Ed., 16, 876 (1977). Similarly, can be used to convert primary alcohols to alkylating agents for use in the alkylation of thiols (e.g. 2-Mercaptopyrimidine, A13382): Tetrahedron Lett., 585 (1972).
