| Silanization reagent | Trimethylsilidazole is the strongest silanization reagent for silanizing hydroxyl groups; it can quickly and smoothly interact with hydroxyl and carboxyl groups Reacts. It does not react with amines or amides, so it can be used to prepare multiple derivatives of compounds containing both hydroxyl and amino groups. It can be used for silylated sugars in the presence of a small amount of water; it is an ideal choice for silylated sugars when sugar needs to be analyzed as a syrup. Can derive most of the steroidal hydroxyl groups that are not blocked and severely blocked. |
| use | used as an antibiotic intermediate, extremely strong silanizing agent high-efficiency silanizing reagent, especially suitable for the synthesis of alcohols and acyl imidazoles, protecting hydroxyl groups in the presence of amino groups. Antibiotic intermediates. An important intermediate for the synthesis of various acyl imidazoles, and also an important intermediate for the synthesis of pyridamide; silylation reagents that protect hydroxyl groups under amine functionalization conditions; powerful silylation reagents, Especially for alcohols; synthesis of acyl imidazoline silylation reagents, protect hydroxyl groups in the presence of amino groups. Antibiotic intermediates. |
