Reagents for New Heteroanellation Reactions. Part 1. Isocyanatedithioketal Reagents.

-The use of isocyanatedithioketal reagents such as (II) in new heteroanellation reactions with 2-aminoesters and 2-aminonitriles is described. Whilst 2-aminoesters provide mono-anellated products containing a pyrimidine moiety (cf. (III), (V)), 2-aminonitriles undergo double anellation furnishing fused imidazopyrimidines (cf. ( VII), (IX)). -(SAUTER, F.;
