A New Chiral Organosulfur Catalyst for Highly Stereoselective Synthesis of Epoxides
A new chrial organosulfide was synthesized through an unexpected Wagner–Meerwein rearrangement. This organosulfide could catalyze the epoxidation reaction of various aromatic aldehydes smoothly with benzyl bromide to give trans‐diaryl epoxides in satisfactory yields (60–84%) with excellent diastereo...

description | A new chrial organosulfide was synthesized through an unexpected Wagner–Meerwein rearrangement. This organosulfide could catalyze the epoxidation reaction of various aromatic aldehydes smoothly with benzyl bromide to give trans‐diaryl epoxides in satisfactory yields (60–84%) with excellent diastereoselectivities (trans:cis=95:5–100:0) and good to excellent enantioselectivities (86–96% ee). |
