SYNTHESIS OF PROTECTED PURPUROSAMINE B AND 6-EPIPURPUROSAMINE B

In relation to the synthesis of antipseudomonal drugs, namely, gentamicin C2 and 3-de-O-methylsporaricin A, a protected purpurosamine B (15) and 6-epipurpurosamine B (13) were synthesized.The key intermediate, methyl 2,3,4,7-tetradeoxy-6-O-(met
