Exo,exo-2,3-diaminoborneol-derived imidazolidinone as chiral auxiliary for asymmetric alkylations

A new camphor-derived imidazolidinone type auxiliary is described. Its acylated derivatives under Na enolate formation and treatment with primary halides give alkylated products in highly diastereoselective manner.
