Cyclopropyl-3,3-dimethylbutan-1-one is an organic compound with the formula (CH)C(O)CH. It is a white solid that is soluble in organic solvents and reacts with water to produce hydrochloric acid. Cyclopropyl-3,3-dimethylbutan-1-one can be used to make other compounds by iodocyclization, including 1,2,4-triazole and 3,4,5-trimethoxybenzene. This reaction proceeds with high stereoselectivity. The synthesis of cyclopropylmethylenecyclohexane can also be accomplished using this reagent. The presence of a hydroxyl group on the ring prevents its use as an oxidant for alkenes or alkynes because it undergoes oxidation by air. Cyclopropyl-3,3-dimethylbutan-1-one also undergoes stere

Amiloride is a medication that belongs to the group of potassium-sparing diuretics. It works by blocking sodium channels in the kidney, which reduces the amount of sodium and water that is reabsorbed into the body. Amiloride has been shown to be effective in human patients. This drug inhibits uptake of pyrazine, which is an active compound in amiloride. Amiloride also inhibits rinm5f, a channel found on renal tubular cells, with inhibitory potency as high as benzene ring. Amiloride has many inhibitors including exchangers such as Na/K-ATPase and Na/H exchanger and other benzene ring compounds such as amiloride itself and ethacrynic acid. The synthesis of amiloride was first reported in 1971 and it can be synthesized by two pathways: from benzene or from ethyl acetate.
