  Toward a total synthesis of an aglycone of spiramycin; installation of the hydroxy groups at C-4 and C-5: a model study

  摘要：

  The stereochemical course of the osmium-mediated bis-hydroxylation of the allylic derivative 6c, whose the structure is closely related to that of a C-1/C-7 fragment of the title aglycone, has been established unambiguously by X-ray analysis of a carboxylic acid derived from one of the two diastereomeric dials which formed.
