摘要:
A redox, hydrogen-acceptor compound, having utility in treating inflammation, is a 1,4-dioxonaphthalene or 1,4-diiminonaphthalene having either a 2,3-double bond, in which case there are 2 and 3-substituents, or a 2,3-single bond. Examples of such compounds are menadione epoxide and water-soluble derivatives of menadione such as menadione bisulphite.

Acylating agents comprising: (A) a 1,2-dicarbonyl compound or its hydroxy-reduction derivative; (B) an enzyme; and (C) at least one compound selected from among (c1) metal compounds and (c2) imide compounds such as N-hydroxyphthalimide. As the 1,2-dicarbonyl compound or its hydroxy-reduction derivative (A), use may be made of biacetyl, 2,3-butanediol, etc. As the metal compounds (c1), use may be made of a cobalt compound such as cobalt acetate. An acyl group can be efficiently introduced into a methine carbon atom by treating a compound carrying a methine carbon atom such as an adamantane derivative by the above acylating agent.

Processes for making bicyclic compounds and precursors thereof, and particularly for making [1.1.1]propellane and bicyclo[1.1.1]pentane and derivatives thereof, utilize continuous flow reaction methods and conditions. A continuous process for making [1.1.1]propellane can be conducted under reaction conditions that advantageously minimize clogging of a continuous flow reactor. A continuous flow process can be used to make precursors of [1.1.1]propellane.

摘要:
A process of reacting (A) a compound capable of forming a stable radical which is selected from among (A1) oxygen compounds having carbon-hydrogen bonds at the position adjacent to the oxygen atom, (A2) carbonyl compounds and (A3) compounds having hydrocarbon groups bearing methyne carbon with (B) a radical-scavenging compound selected from among (B1) unsaturated compounds, (B2) compounds having hydrocarbon groups bearing methyne carbon, and so on in the presence of molecular oxygen by the use of an imide catalyst represented by general formula (1) or the like to thereby obtain an adduct of the compound (B) with the compound (A), a product of substitution of the compound (B) with the compound (A), or oxides of both. In said formula, R and R are each hydrogen or the like, or alternatively R and R may be united to form a double bond or an aromatic or nonaromatic ring; and X is oxygen or hydroxyl. This process makes it possible to efficiently produce various organic compounds under mild conditions through addition or substitution by the use of molecular oxygen.
