| titleOfInvention | Method for producing optically active bicyclo derivative and novel bicyclo derivative |
| abstract | (57) Abstract: Provided is an optically active bicyclo derivative which can be an important synthetic intermediate of many natural products and / or bioactive compounds by a catalytic asymmetric intermolecular-intramolecular tandem nitroaldol reaction. . An aldehyde of the formula (1) is obtained by an asymmetric intermolecular-intramolecular tandem nitroaldol reaction using an asymmetric synthesis catalyst using a metal complex obtained by reacting an optically active binaphthol or a binaphthol derivative with a rare earth compound. From the compound and nitromethane, an optically active bicyclo derivative of formula (3), which is important for supplying raw materials for medicines, pesticides, fragrances, and liquid crystal intermediates, can be produced in a single step. Embedded image [In the formulas (1) and (3), R 1 represents an alkyl group having 1 to 3 carbon atoms, Y represents O, S or H 2 , m represents an integer of 2 to 4, and n represents 2 to 2. Represents an integer of 5. ] |
