Summary
Syntheses of 11-amino-5,6-dihydronaphtho[1′,2′:4,5]thieno[2,3-d]pyrimidine (8) and its 10-oxide 7 from 2-amino-1-cyano-4,5-dihydronaphtho[2,1-b]thiophene and its derivatives are described. Several open chain tetrahydronaphthylidene derivatives and a substituted pyrimidine derivative9 were also prepared.
