摘要:
Disclosed herein is a process for the preparation of erythromycin derivatives, or pharmaceutically acceptable salts thereof, which contain an optionally substituted propargyl group at the 6-O-position.
摘要:
The invention relates to a process for preparing quinoline-substituted carbonate and carbamate compounds, which are important intermediates in the synthesis of 6-O-substituted macrolide antibiotics. The process employs metal-catalyzed coupling reactions to provide a carbonate or carbamate of formula (I) or (II) or a substrate that can be reduced to obtain the same.
摘要:
A compound of formula (I), or a pharmaceutically acceptable salt thereof is disclosed, as well as processes for and intermediates in the preparation thereof, and a method of antagonizing endothelin.
