Tethered Aminohydroxylation: Synthesis of the β‑Amino Acid of Microsclerodermins A and B

The utility of the tethered aminohydroxylation (TA) has been demonstrated by synthesis of the complex β-amino acid residue of microsclerodermins A and B. The TA provided a regio- and stereoselective functionalization of a complex homoallylic alcohol. The route includes late-stage introduction of the aliphatic side chain <i>via</i> a cuprate addition and cross metathesis, a tactic designed to render the synthesis applicable to other microsclerodermins
