N-Acetylated 1,4,7- and 3,4,7-trideoxypancratistatin analogues 10 and 13 were synthesised from partially saturated phenanthridinones, 6 and 7, respectively via epoxidation and trans opening of the epoxides. Compounds 16 and 17, cis analogues of 13 were also synthesised from 7 via cis dihydroxylation with catalytic osmium tetroxide and N-methylmorpholine N-oxide. The stereoisomers obtained were separated
