摘要:
The invention relates to a process according to scheme for preparing 2-methylpyrrolidine and, more particularly, specific enantiomers of 2-methylpyrrolidine. The corresponding 2-Iodomethylderivatives intermediates also are described. Scheme 1 (I)
摘要:
In one aspect, the invention relates to a process for preparing 6-O-substituted erythromycin derivatives comprising reacting 2'-substituted and optionally 4'-substituted 9-oxime erythromycin derivatives with an alkylating agent in the presence of a palladium catalyst and phosphine. In another aspect, the invention relates to processes for preparing 6-O-substituted erythromycin ketolides using the palladium-catalyzed alkylation reaction.
摘要:
A process of preparing 6-O-alkylerythromycin A using 9-oximesilyl erythromycin A derivatives is provided. 9-Oximesilyl- and 6-O-alkylerythromycin A derivatives used in the preparation of 6-O-alkylerythromycin A are also provided.
摘要:
The disclosed invention relates to novel 3'-N-O, 9-O-oxime protected, 6-O-alkyl erythromycin derivatives of formula (I), a process of preparing the same. The invention also relates to a process of preparing 6-O-alkyl erythromycin A by eliminating the 3'-N-oxide group and 9-O-oxime protecting groups and optionally deprotecting the hydroxy groups at the 2'- and 4''- positions under suitable reaction conditions.
