| abstract | PURPOSE: To obtain simply in high yield a compound useful as a germicide, an anti-inflammatory agent, an activator for polymerization, etc., by reacting thiirane with an active methylene compound in the presence of a strong base. n CONSTITUTION: A thiirane shown by the formula I (R 1 is alkyl, aryl, or H; R 2 and R 3 are alkyl or H) is reacted with an active methylene compound shown by the formula II (R 4 is alkyl; R 5 is alkyl or alkoxy) in the presence of a base (e.g., sodium ethoxide) in a solution of an alkali catalyst (e.g., sodium hydride) in a solvent such as ethanol, etc., at room temperature or under heating to give the aimed compound shown by the formula III or formula IV. The compound shown by the formula I is easily synthesized from a corresponding epoxide by the use of thiourea or potassium thiocyanate and the compound shown by the formula II is inexpensively on the market and easily obtainable. n COPYRIGHT: (C)1987,JPO&Japio |
