CAS: 826-86-8

2-Methyl-3,4-dihydro-2H-1-benzothiopyran-4-one is a synthetic compound that is used in the synthesis of thioflavones. It can be prepared by cyclodehydration of acetophenone with chlorides and sulfur. This reagent has been shown to react selectively with nucleophiles such as lithium diisopropylamide and triflic acid at the 2 position of the aromatic ring to form an intramolecular cyclic compound. Cyclodehydration of 2-methylbenzothiophene can also produce this compound.
