摘要：

The enantiomerically pure ruthenium porphyrin 3 was synthesized in very high yield by refluxing the porphyrin 2 with Ru-3(CO)(12) in phenol; its subsequent use in the catalytic asymmetric epoxidation of olefins with 2,6-dichloropyridine N-oxide as terminal oxidant, to afford epoxides in good yields and with enantioselectivities up to 77%, is reported.
