摘要：
New C-2-chiral porphyrins bearing cyclohexyl substituents at ortho position of the meso-phenyl groups have been synthesized. Their ruthenium complexes have been used as enantioselective catalysts for the epoxidation of styrene derivatives using 2,6-dichloropyridine-N-oxide as oxidant with moderate selectivity (35% e.e. with 1,2-dihydronaphtalene).
