The competitive muscarinic receptor antagonist fesoterodine is a congener of tolterodine and has better efficiency compared to tolterodine. In this study, we present an efficient synthesis of the fesoterodine intermediate 3-(3-diisopropylamino-1-phenylpropyl)-4-hydroxybenzaldehyde from ethyl benzoylacetate by Friedel-Crafts alkylation in the presence of an acid as a key reaction step. The synthesis is carried out by the reduction of the ketoester to a 1,3-diol, diisopropylamine substitution, and Friedel-Crafts alkylation, followed by reduction and chiral resolution.
Background: Little is known about the specific types of childhood trauma and their relationship to treatment-related issues in major depressive disorder (MDD). This study examined trauma experiences and treatment-related variables in outpatients with MDD at a psychiatric department of a university hospital in Korea. Methods: First, 75 outpatients with MDD were compared to medical outpatients without MDD matched by age, sex, income, and educational qualifications. Both groups completed the Life Stressor Checklist-Revised, which assesses comprehensive life events. Second, treatment-related variables and medication compliance measured by the Compliance Rating Scale were investigated for the two-year period after the initial assessment. Results: The MDD group had experienced a significantly higher number of lifetime traumas than the control group (p=0.003), including more frequent witnessing of family violence (p<0.001), adulthood physical assault by a family member (p<0.001), and childhood emotional abuse (CEA) (p<0.001). CEA was associated with early onset of the first depressive episode and premature termination of pharmacotherapy; childhood physical neglect was associated with premature termination and less time in therapy. Conclusion: Our findings support the important influence of childhood emotional trauma and its relationship to treatment retention.
N-Sulfonylformamidines were synthesized from N-sulfonylsulfonamides by reacting with p-toluenesulfonyl chloride (TsCl) and N,N
-disubstituted formamides. In this reaction, it was expected that mixing TsCl with the N,N-disubstituted formamide would generate an iminium salt (Vilsmeier reagent). The reaction avoids the use of metal catalysts and hazardous reagents, and the desired N-sulfonylformamidines were obtained in 60% to quantitative yields.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
