摘要:
A 4-substituted γ-lactone is produced by introducing a 1-alkynyl group into the 1-carbon atom of 2,3-O-isopropylidene-D-ribofuranose, cleaving the resulting compound at the diol part to give a lactol, oxidizing it into a lactone, hydrolyzing the ketal group of the lactone, reducing the hydrolyzate, removing the 2- and 3-hydroxyl groups, and hydrogenating the double bond between the 2- and 3-carbon atoms of the product.

A 4-substituted η-lactone is produced by introducing a 1-alkynyl group into the 1-carbon atom of 2,3-O-isopropylidene-D-ribofuranose, cleaving the resulting compound at the diol part to give a lactol, oxidizing it into a lactone, hydrolyzing the ketal group of the lactone, reducing the hydrolyzate, removing the 2- and 3-hydroxyl groups, and hydrogenating the double bond between the 2- and 3-carbon atoms of the product.
摘要:
An attractant having attraction activity in relation to Tribolium Confusum J., which contains 2,6-dimethyl-1-octanol as a component exhibiting attraction activity. 2,6-dimethyl-1-octanol can be diluted with an appropriate solvent, or carried by an appropriate solid-phase carrier in the form of tablets. The attractant can be effectively used in lure trapping.
