The synthests of 2-alkylnaphtho- and 2-alkylbenzopyranyl salts fromβ-chlorovinylketones

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Summary

  1. 1.

    A new method of preparing 2-alkylnaphthopyranyl salts from the easily accessible alkyl-β-chlorovinyl-ketones is described, The method makes it possible to prepare 2-alkylnaphthopyranyl salts in good yield.

  2. 2.

    It is shown that it is possible to convert the ferrichlorides obtained into the corresponding alkylnaphthyl-pyranyl perchlorates.

  3. 3.

    When the 2-methylnaphthopyranyls were treated with alkali, 2-hydroxynaphthaldehyde-1 was obtained; this proves the structure of the naphthopyranyl salts.

  4. 4.

    It is shown that phenol also reacts with methyl-\-chlorovinylketone to form 2-methylbenzopyranyl salts.
