摘要: 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 substituents to a 1-N-imino substituent, converting the imino to an ethylamino, deprotecting the compound and recovering netilmicin. Also disclosed are novel intermediate compounds.

摘要: An improved process for converting gentamicin B to isepamicin comprising forming 3,6′-di-N-formylgentamicin B, acylating the 1-amino group with an N-protected (S)-isoserine compound and removing all the blocking groups under conditions which result in high yields of isepamicin. A novel formylating agent, 2-formylmercaptobenzothiazole, and intermediate compounds are also disclosed.

摘要: Novel isoserine compounds such as N;O-diformyl-(S)-isoserine and N-formyl-(S)-isoserine are described and used in a process for converting gentamicin B to isepamicin. Active esters are formed by reaction of the isoserine compounds with N-hydroxybenzotriazole, N-hydroxysuccinimide, imidazole, N-hydroxyphthalimide, N-hydroxy-5-norbornene-2,3-dicarboximide and the like in the presence of a coupling agent such as dicyclohexyl- carbodiimide.
