✦ Synopsis

Diastereoselective Cyclopropanation of α,β-Unsaturated Acetals of a Novel Camphor-Derived Chiral Auxiliary.

-2-exo-3-exo-Dihydroxybornane-10-sulfonate (III) proves to be a highly efficient chiral auxiliary for the asymmetric Simmons-Smith cyclopropanation of α,βunsaturated acetal derivatives [cf.

(V)→(VII)]. -(KAYE, PERRY T.;
