V. Michelet et al., A new synthetic approach toward (+)-ambruticin analogs: Preparation of a C10-C11 cis-isomer fragment, EUR J ORG C, (11), 1999, pp. 2885-2892
A new methodology has been applied to synthesize an isomer of the west part
of (+)-ambruticin based on an efficient asymmetric de novo access to the A
unit and sequential stereospecific reactions catalyzed by Pd-0 for the con
struction of the B unit.
