A new asymmetric 1,4-addition method: application to the synthesis of the HIV non-nucleoside reverse transcriptase inhibitor DPC 961

The asymmetric synthesis of the HIV non-nucleoside reverse transcriptase inhibitor (NNRTI) DPC 961 is achieved in three steps with an overall yield of >55%. The asymmetry is induced by the chiral auxiliary (R)-(+)-α-methylbenzylamine, utilizing a new asymmetric 1,4-addition protocol.
