5-(Tetradecyloxy)-2-furancarboxylic acid (91, RMI 14514) was found to lower blood lipids and to inhibit fatty acid synthesis with minimal effects on liver weight and liver fat content. This fatty acid-like compound represents a new class of hypolipidemic agent; it is effective in rats and monkeys. The compound resulted from discovery of hypolipidemic activity in certain beta-keto esters, postulation

Methods of applying cyclopropene derivatives and compositions thereof to block ethylene receptors in plants are disclosed. One such method comprises applying to the plant an effective ethylene response-inhibiting amount of cyclopropene derivatives or compositions thereof. Also disclosed are methods of inhibiting abscission in plants, methods of prolonging the life of cut flowers, methods of inhibiting ripening of picked fruits, and methods of inhibiting ripening of picked vegetables.
alkyl p-tolyl sulfones with dimethyl disulfide could be easily hydrolyzed by CuCl2–SiO2 to give the corresponding ketones in fairly good yields. This method was applied to the synthesis of DouglasFir Tussock Moth Pheromone.

A novel organic compound 5-chloro-1-bromo-1-pentyne is disclosed. This compound is prepared by the reaction of 5-chloro-1-pentyne with potassium hypobromite in an aqueous medium at a temperature of 10 to 40 °C in a high yield. The compound is useful as an intermediate for the synthesis of Z-6-heneicosen-11-one which is known as a sex pheromone compound of a noxious insect Dougals-fir tussock moth notorious in the western North-American forests.
