Abstract:

Polyoxins are natural nucleoside peptides isolated from strains of Streptomyces cacoi var. asoensis which present a relevant antifungal activity by inhibition of chitin synthase. The preparation of polyoxins is focused on the synthesis of the α-amino acid portion, (+)-polyoxamic acid, since the synthesis of its nucleoside residue is well described in literature. The purpose of this work is to propose a new approach to the synthesis of (+)-polyoxamic acid and derivatives starting from an asymmetric Morita-Baylis-Hillman (MBH) reaction. The antibacterial profile of these derivatives will be also evaluated.
