A Practical and Controllable Enantioselective Synthesis of 2-Phenyl-1cyclopropanecarboxylates via a Camphor-Derived Sulfonium Ylide

We have developed a practical and controllable enantioselective synthesis of 2-phenyl-1-cyclopropane-carboxylates via camphor-derived sulfonium ylide. The procedure has many advantages such as cheap starting materials, facile synthetic procedures, good yields, excellent diastereoselectivities and high enantioselectivities.
