Plant Growth-regulating Activities of 4-Methoxydiphenylmethanes and Their Related Compounds

“…3 well. Higher activities for 3' -chI oro (4), 3' -bromo (8), and 4'-dimethylamino (21) derivatives than were expected were also found.…”

Stereochemistry of Reduction of Ketones by Complex Metal Hydrides

“…The product, previously reported as A4-cholestene (13), was shown to be a mixture of cholestene with about 10% cholestane. Hydrogeilolysis has been observed in the reduction of other compounds by this reagent (14,15). Cholest-5-en-3-one gave a mixture which contained Can.…”

Inhibitors of Cholesterol Biosynthesis. 2. Hypocholesterolemic and Antioxidant Activities of Benzopyran and Tetrahydronaphthalene Analogs of the Tocotrienols

“…An aluminum chloride-lithium aluminum hydride (LAH) mixture (2:1) works well for the reduction of electron-rich benzopyranones but gives increasing amounts of 3,4-dehydrobenzopyrans upon ring deactivation. 12 The 3,4-dehydrobenzopyrans resulting from elimination rather than from reduction are difficult to separate from the desired products.13 Significant amounts of ether-cleavage products were obtained when the C-2 and C-8 positions are hydrogen-substituted. In cases where elimination and/ or ether cleavage was problematic, an alternative reduction method was employed.…”
