-hex-l-enitol were prepared by substitution of the allylic ester function of 1,5-anhydro-3,4-di- O -benzoyl-2,6-dideoxy- l - arabino -hex-l-enitol with sodium azide, followed by reduction with lithiumaluminumhydride. Glycosidation was performed with various alcohols, in particular daunomycinone. In the latter case, the partial synthesis of 4′-epi- and 3′,4′-epi-daunorubicines was accomplished in

3'-[2-(Selenoaryl)acetamido]epi-daunomycin derivatives 2a-d and 4'-[2-(selenoaryl)acetoxy]-N-(trifluoroacetyl)epi-daunomycin derivatives 4a-e were synthesized from epi-daunomycin 1d and N-trifluoroacetyl epi-daunomycin 3, respectively. These new compounds were assayed against human stomach cancer SGC-7901 and human leukaemia HL60.
