The synthesis and evaluation of novel azetidine lincosamides 1 are described. Eleven new (3-trans-alkyl)azetidine-2-carboxylic acids were synthesized via alkylation of N-TBS-4-oxo-azetidine-2-carboxylic acid and subsequent elaboration then coupled to 7-chloro-1-methylthio-lincosamine. The resulting lincosamides differ from the drug clindamycin in both the size of the ring and the position/structure
描述了新型氮杂环丁烷林可酰胺1的合成和评价。通过N-TBS-4-氧代-氮杂环丁烷-2-羧酸的烷基化反应合成了十一种新的(3-反-烷基)氮杂环丁烷-2-羧酸,随后进行精制,然后与7-氯-1-甲硫基-林可胺偶联。所得的林可酰胺与药物克林霉素在环的大小和烷基侧链的位置/结构上均不同。研究了该系列中的SAR,并注意了氮杂环丁烷环1和3位的烷基变体。
