PURPOSE: To obtain an optically active epoxide useful for a synthetic intermediate for medicines, agrochemicals, etc., ferroelectric liquid crystal, etc., by reacting an olefin compound with oxygen in the presence of both an optically active metal compound such as a new Mn (III) complex, etc., and an aldehyde compound.
CONSTITUTION: An olefin compound (e.g. 1,2-dihydronaphthalene) is reacted with oxygen in the presence of both an optically active metal compound composed of a new manganese (II) compound of the formula (R2 and R2 are H, alkyl or aryl; R3 to R5 are H, alkyl, aryl, acyl or alkoxycarbonyl; X- is anion) and an aldehyde compound (e.g. pivalic aldehyde) at room temperature in an oxygen atmosphere under stirring to give the objective optically active epoxide [(1R,2S)-epoxy-3,4-dihydronaphthalene, etc.] useful for a synthetic intermediate for physiologically active compounds such as medicines, agr'ichemicals, etc., a functional material such as ferroelectric liquid crystal, etc., and a synthetic intermediate for fine chemicals.
