system. Herein, we report our strategy towards this class of natural products, that led to the identification of an electronically well-balanced spiroketalization precursor and eventually culminated in the preparation of an unnatural 4′-silyl-substituted γ-rubromycin derivative in racemic form. In the course of this study, we additionally introduced a new type of γ-silylated allylic phosphonate reagents

oxime (8) in high yield. Controlled bromination of the aromatic ring gave the monobromo oxime (9), the dibromo oxime (10), or the spiroisoxazoline (11) depending upon reaction conditions. Synthesis of the known metabolite verongamine (15) was achieved by oxidation of O-methyl bromotyrosine methyl ester and amidation of the resulting oxime ester (14) with histamine. The mono- and di-bromotyrosine oxime derivatives
Battling the flu: Zanamivir (Relenza) is widely prescribed as an anti‐influenza drug. It contains a vicinal amino alcohol, which is in an anti orientation, and is readily accessed by an anti‐selective catalyticasymmetricnitroaldol (Henry) reaction promoted by a heterobimetallic complex (see scheme; PMB=p‐methoxybenzyl). Additional synthetic manipulation of the nitroaldol product allowed the enantioselective
