| abstract |
A high yielding process for converting 3,2',6'-tri-N-acetyl sisomicin to netilmicin comprising the step of silylating the starting material at the 5,2' positions, and optionally at the 4' position, converting the 1-amino substituent to a 1-N-imino substituent, converting the imino to an ethylamino, deprotecting the compound and recovering netilmicin. Also disclosed are novel intermediate compounds. |
