โœฆ Synopsis

C-Acylation of Electron-Rich Heterocyclic Compounds with Kirsanov Isocyanate.

-Pyrroles (I), indoles (VI), indolizines (IX), and 2-methylfuran (XI) are smoothly and almost regioselectively C-acylated with isocyanatophosphoryl dichloride (Kirsanov isocyanate). The resulting heteroaryl-substituted dichlorides provide a convenient access to a variety of products by further derivatization.

Regioselective Acylation of Heterocyclic Ketene Aminals with Acetyl Chloride. -Acylation of ketene aminals (I) affords exclusively the N-acylated products (IV), while in the presence of triethylamine and Hg(CN)2 the C-acylated products (III) predominate together with (IV) as minor products. The (E)
