General description

1-Hexyn-3-ol is a terminal propargylic alcohol. It undergoes microwave-accelerated coupling-isomerization reaction (MACIR) with (hetero)aryl halides to afford the corresponding enone.

Application

1-Hexyn-3-ol may be used in the synthesis of racemic 3-hydroxy-2-hexanone. It may also be used in the preparation of 1,2,3-triazoles.

We report the identification of a novel pheromone structure from males of the cerambycid beetle Tylonotus bimaculatus Haldeman (Cerambycinae: Hesperophanini), a species native to eastern North America. Volatiles collected from adult males contained (2S,4E)-2-hydroxyoct-4-en-3-one (71%), (3R,4E)-3-hydroxyoct-4-en-2-one (15%), (E)-4-octen-2,3-dione (13%), and
