  Dispiroketals in synthesis (part 8): Regioselective protection of D-glucopyranose substrates

  摘要：

  A new process for the efficient regioselective formation of 1,8,13,16-tetraoxadispiro[5.0.5.4]hexadecanes (dispiroketals) of various D-elucopyranosyl substrates by the chiral recognition of enantiomeric trans 1,2-diol relationships is described. This was achieved using the novel enantiomerically pure 2,2'-disubstituted 3,3',4,4'-tetrahydro-6,6'-bi-2H-pyrans 1, 2 and 11. New conditions for the removal of dispiroketal protecting groups are presented.

  摘要：

  Chiral recognition of enantiomeric trans-1,2-diol relationships leading to regioselective formation of 1,8,13,16-tetraoxadispiro[5.0.5.4] hexadecanes (dispiroketals) of various D-glucopyranoside, D-galactopyranoside and D-mannopyranoside substrates is described. Regioselectivity is achieved using the enantiomerically pure disubstituted tetrahydro-6,6'-bi-2H-pyrans 1, 2, 3, 4 and 5. Facile removal of the dispiroketal protecting group from a number of the sugar adducts has been achieved.
