Abstract
Disclosed herein is a new procedure for preparing the C.1-2,4-pentadienyl derivatives of 2-deoxyhexopyranoses, as well as a new procedure for allylation of daunosamine. These methods are particularly useful for the preparation of intermediates in the synthesis of adriamycin C-glycosidic analogs which are useful anti-tumor agents. These methods provide the first enabling disclosure of methods to prepare these desired adriamycin and anthrocyclinone C-glycosidic analogs.
