TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Material: The protonic acid can be hydrogen chloride (HCl), hydrogen bromide (HBr), or sulfuric acid (H2SO4).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Material: The chiral secondary amine catalyst is of formula (V). The protonic acid is fluoroboric acid (HBF4), fluorophosphoric acid (HPF6), acetic acid (CH3COOH), trifluoroacetic acid (CF3COOH), trifluoromethanesulfonic acid (CF3SO3H), benzoic acid, o-fluorobenzoic acid, m-fluorobenzoic acid, phenyl acetic acid, p-methyl benzoic acid, o-nitryl benzoic acid, m-nitryl benzoic acid, o-trifluoromethyl benzoic acid, m-trifluoromethyl benzoic acid, p-trifluoromethyl benzoic acid, benzene sulfonic acid, p-methyl benzene sulfonic acid, p-dodecyl benzene sulfonic acid, alpha -naphthalene sulfonic acid, beta -naphthalene sulfonic acid, alpha -rhodofix, oleic acid, stearic acid, normal-dodecyl sulfonic acid, or methacrylic acid. It is organic protonic acid, preferably benzoic acid, p-fluorobenzoic acid, p-nitryl benzoic acid, o-trifluorotolylene formic acid or p-trifluorotolylene formic acid. Preferred Composition: The mol ratio of the nitroolefin derivatives/chiral secondary amine catalyst/protonic acid/water is 1:0.2:0.2:34. Preferred Condition: The reaction temperature is 25 degrees C and the reaction time lasts for 12-36 hours. Preferred Method: The separation of the reaction solution is conducted by extracting the reaction solution with ethyl acetate, stewing for layering, fetching the residual of the organic layer after the solvent is removed by distilling, using the eluting solution of petroleum ether and ether with volume ratio of 7:3 as the eluent and carrying out column chromatographic separation and purification to obtain the chiral bicyclic compound. Preferred Definitions:    R1-R3=H or methyl;    R4=2-methoxyphenyl, 3-methoxyphenyl, 4-methoxyphenyl, 4-methylphenyl, Ph, 4-fluorophenyl, 4-chlorophenyl, 3-bromophenyl, 4-bromophenyl, 3-nitrophenyl, 4-trifluoromethylphenyl or furyl.
