Abstract
Bis(trimethylsilyl)pyrimidine bases were treated directly with 1, 3-dioxolane (or 2-methyl-1, 3-dioxolane), chlorotrimethylsilane and a metal iodide, such as KI or NaI, in acetonitrile at room temperature to afford acylopyrimidine derivatives, including 2-thiopyrimidine derivatives, in good yields. Introduction of an acyclic chain into 2-thiopyrimidine bases, however, necessitated the use of 2 eq of the reagents.
