    • Usually better results could be obtained in the presence of tertiary amine-thiourea catalyst with strong electron-withdrawing group.

    • Although the formation of racemic product from 2g and 3a catalyzed by 1c is not clear yet, the following plausible catalytic model might account for the observed results.{A figure is presented}
