The asymmetric cycloaddition of TIPS nitronate catalyzed by “Cu(II)-bisoxazoline” gave the 2-isoxazoline product in 95% yield, which was converted into tert-butyl (3S,5R)-6-hydroxy-3,5-O-isopropylidene-3,5-dihydroxyhexanoate in 14 steps through a β-hydroxy ketone.

The use of molecular editing in the elucidation of the mechanism of action of amphotericin B is presented. A modular strategy for the synthesis of amphotericin B and its designed analogues is developed, which relies on an efficient gram-scale synthesis of various subunits of amphotericin B. A novel method for the coupling of the mycosa-mine to the aglycone was identified. The implementation of the approach has enabled the preparation of 35-deoxy amphotericin B methyl ester. Investigation of the antifungal activity and efflux-inducing ability of this amphotericin B congener provided new clues to the role of the 35-hydroxy group and is consistent with the involvement of double barrel ion channels in causing electrolyte efflux. 2009 Wiley-VCH Verlag GmbH & Co.

(Chemical Presented) A modular strategy for the assembly of amphotericin B analogues with modifications in the macrolactone ring relies on the efficient gram-scale synthesis of all major and minor motifs of amphotericin B. Proof of concept has been achieved by the preparation of the 35-deoxy aglycone en route to the long-sought-after 35-deoxy analogue of amphotericin B.
