Enantioselective synthesis of deoxy analogues of pyranonaphthoquinone antibiotics (+)-nanomycin A methyl ester, (+)eleutherin, (+)-allo-eleutherin, and (+)-thysanone was achieved in good overall yield with high enantio- and diastereoselectivity from the common intermediate (R)-3-(2,5-dimethoxyph.enyl) propane-1,2-diol. The intramolecular oxaPictet-Spengler cyclization of 6-a:ryl-l.,3-dioxolone was de-veloped for the first time and utilized in the enantioselective synthesis of (H-)-deoxynanomycin A methyl ester, whereas the intermolecular oxa-Pictet-Spengler cycllzation strategy was applied to the enantioselective synthesis of deoxy analogues of (+)-eleutherm, (+)-allo-eleutherin, and. (+)-thysanone,

A short and efficient organocatalytic enantioselective formal synthesis of HRV 3C-protease inhibitor (1R,3S)-thysanone is achieved in a nine-step with 98.7% enantiomeric excess, by employing l-proline-catalyzed asymmetric α-aminooxylation of aldehyde and
