Abstract

We have succeeded in synthesizing optically active -methyl-4-nitro-3a,4,5,6,7,7a-hexahydro-1-indanone (3b) with 65% ee in one-pot from aldehyde 1 and nitromethane using a tandem inter-intramolecular catalytic asymmetric nitroaldol reaction promoted by LnLi(3)tris(R)-bina phthoxide) (LnLB; Ln = lanthanoid) and after crystallization 3b with 79% ee was isolated in 41% yield. In addition, after recrystallization, the optical purity of 3b was increased to 96% ee. (C) 1997 Elsevier Science Ltd.
