The preparation of the disaccharide 4 - O - (3,4 - di - O - acetyl - 2,6 - dideoxy - α - l - lyxo - hexopyranosyl) - 2, 3,6 - trideoxy - 3 - trifluoroacetamido - l - lyxo - hexopyranose, 11c, the N,N' - dimethyl derivative of which occurs naturally in numerous anthracyclines, is described. Glycosidation with daunomycinone followed by removal of the protecting groups led to 4' - O - (2 - deoxy - l -
二糖4- O-(3,4-二-O-乙酰基-2,6-双脱氧-α-1-lyxo-己吡喃糖基)-2,3,6-三脱氧-3-三氟乙酰氨基-l- lyxo的制备描述了-六吡喃糖11c,其N,N'-二甲基衍生物天然存在于许多蒽环类中。用柔红霉素进行糖基化,然后除去保护基,产生4′- O-(2-脱氧-1-岩藻糖基)柔红霉素。
