Reactions of uracils, 24. Multiple anellation to uracils and their analogs - An approach to Nevirapine-type tricycles

Starting with 6-amino-1,3-dimethyluracil 1 a structural analog of the NNRTI Nevirapine 16 is synthesized in a sequence of two ring anellations and a Beckmann rearrangement. The anellation behavior of 3 is studied in general leading to the anellated systems 5, 7a-c, 12 a-c.
