The key aetheramide A intermediate with the natural (R,R,R) configuration along with the one having the unnatural (R,S,R) configuration was synthesized. The synthesis of both stereoisomers was accomplished by Suzuki coupling of two advanced chiral building blocks: (R,R)- and (R,S)-vinylboronates and an (R)-iodoalkene. The former was prepared from (R)-mandelic acid, and the latter was prepared by enantioselective allylation of 3-iodoacrylaldehyde.

A highly diastereoselective and enantioselective method for the multicomponent aziridination of chiral aldehydes has been developed with BOROX catalysts of the VANOL (3,3′-diphenyl-2,2′-bi-1-naphthol) and VAPOL (2,2′-diphenyl-(4-biphenanthrol)) ligands. Very high to perfect catalyst control is observed with most all substrates examined including aldehydes with chiral centers in the α- and β-positions. High catalyst control was also observed for a number of chiral heterocyclic aldehydes allowing for the preparation of epoxy aziridines, bis(aziridines) and ethylene diaziridines. Application of this reaction in the synthesis of β3-homo-d-alloisoleucine and β3-homo-l-isoleucine is reported.

A simple and highly concise strategy has been developed for the stereoselective total synthesis of leiocarpin C starting from commercially available mandelic ester. The strategy utilizes the OsO4-catalyzed cis-hydroxylation and selective reduction with K-Selectride as key steps. Copyright
