General description

4-Ethynylanisole forms the corresponding propargyl aldehyde in good yield directly from DMF-dimethyl acetal without the need for making an acetylide salt. 1,3-dipolar cycloaddition of acceptor-cyclopropylmethylsilanes affords functionalized cyclopentenes in good yields.

4-Ethynylanisole can be used as a building block in organic synthesis and also used in sonogashira coupling reactions.

Application

1,3-dipolar cycloaddition of acceptor-cyclopropylmethylsilanes affords functionalized cyclopentenes in good yields.
4-Ethynylanisole was used:
  • in the synthesis of photoluminescent 1,2-dihydrophosphinines via a [4 + 2] cycloaddition
  • along with an arylboronic acid and sodium azide in a copper-catalyzed, three-component synthesis of trisubstituted 1,2,4-triazoles
  • in a study of a gold (III)-catalyzed hydroamination of alkynes leading to N-vinylindoles.
Forms the corresponding propargyl aldehyde in good yield directly from DMF-dimethyl acetal without the need for making an acetylide salt.

The addition of 4-trifluoromethyl-1-ethynylbenzene, phenylacetylene, or 4-ethynylanisole to P-mesityldiphenylmethylenephosphine, 1, produced photoluminescent 1,2-dihydrophosphinines 4a-c, respectively, in quantitative yield via a [4 + 2] cycloaddition. Limited reactivity was observed between 1 and non-aromatic alkynes.

A highly efficient double-hydroamination reaction of o-alkynylanilines with terminal alkynes leading to N-alkenylindoles was developed by using gold(III) as a catalyst under neat conditions. [reaction: see text].
