Abstract

The synthesis of new chiral auxiliaries, 7-alkyl substituted cis-1-amino-2-indanol derivatives, was established by the Diels–Alder reaction of 1-substituted dienes with cyclopentenone followed by the asymmetric epoxidation of the resulting indene derivatives and then the Ritter reaction. These bulky cis-aminoindanol derivatives are very effective as chiral auxiliaries and nitrogen sources in the asymmetric 6π-azaelectrocyclization. The ...
