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.
