  Amino Acid-Derived Chiral Acyl Nitroso Compounds: Diastereoselectivity in Intermolecular Hetero Diels-Alder Reactions

  摘要：

  The diastereoselectivities of chiral acyl nitroso dienophiles derived from optically pure N-protected alpha-amino hydroxamic acids have been determined in intermolecular hetero Diels-Alder reactions. The cycloaddition reactions afforded synthetically useful quantities of functionally rich, optically pure cycloadducts, useful for the preparation of a variety of compounds of potential biological interest. Molybdenum hexacarbonyl reduction of the cycloadducts gave optically pure allylic alcohols. Osmium tetraoxide-catalyzed dihydroxylation of several bis-allylically substituted intermediates gave only the diastereomerically pure diols corresponding to naturally occurring 2',3'-dihydroxynucleoside analogs.
