The catalytic enantioselective synthesis of (+)-epi-cytoxazone has been accomplished in four steps from p-methoxybenzaldehyde N-Boc-imine with good diastereo- and enantioselectivity. This approach involves asymmetric Mannich reaction of an aldehyde with N-Boc-imine using the novel 2-pyrrole-derived imidazolidinone as an organocatalyst. (C) 2008 Elsevier Ltd. All rights reserved.
