일반 설명
Dichloromethylene-dimethyliminium chloride (Vilsmeier reagent) reacts with o-acetaminophenols under Meth-Cohn conditions to yield 2-formylpyrido[2,1-b]benzoxazoles.
애플리케이션
Dichloromethylene-dimethyliminium chloride was used as reagent in the synthesis of selenourea and (R)-2-(2-chloroethyl)pyrrolidine-1-carboxylic acid ethyl ester. It was used for introducing amide chloride group into activated substrates.

o-Acetaminophenols (2) reacted with Vilsmeier reagent under Meth-Cohn conditions to yield 2-formylpyrido[2,1-b]benzoxazoles (5) unexpectedly besides the known compounds 2-(benzoxazol-2'-yl)-3-dimethylaminoacroleins (4). Refluxing 4 in acetic anhydride gave 4-formylpyrido[2,1-b]benzoxazoles (6), an isomer of 5. Both 5a and 6a were structurally characterized by
