Popis: 3-Carbonyl substituted isothiochromans (3,4-dihydro-1H-2-benzothio- pyrans) (3) were synthesized in moderate yields in a one-pot process from dibromide (1) and 2-mercaptocarbonyl compounds (2). This method could be also extended to the synthesis of tetracyclic 1-H-anthraceno [2,3-c]thiopyran (5)
