- A facile synthetic method for the construction of 2-substituted-4-oxo-4H-quinolizine-based core structure has been successfully developed. The synthesis made use of a one-pot Stobbe condensation followed by cyclization starting from the commercially available 2-pyridinecarbaldehyde. The structure of the formed 4-oxo-4H-quinolizine-2-carboxylate was fully confirmed by mass spectra, H-1 NMR and C-13 NMR, correlation spectrography, heteronuclear multiple bond correlation, and heteronuclear single quantum coherence (HSQC) spectra. The ethyl carboxylate moiety was then further functionalized via direct aminolysis by a range of amines to afford the corresponding 4-oxo-4H-quinolizine-2-carboxamides 4a-i in moderate to good yields.

- This review covers the literature from 2005 to till date. Oxidation chemistry is a dynamic field of organic synthesis as it keeps evolving with the passage of time. There is a recent surge in that area to switch over from inorganic oxidants to organic oxidants. The oxidation of heteroatom is an intriguing task for the synthetic chemists, as it requires mild oxidant with no harmful side products. Dimethyldioxirane serves as a super-effective oxidant as it shows high functional group tolerance and possess acetone as byproducts which is also eco-friendly. This review summarizes the heteroatom oxidation of sulfur, nitrogen, iodine, selenium, phosphorous, and platinum atoms using DMDO as an oxidant.

- OBJECTIVE: There is limited knowledge about how adolescents with asthma view their disease in daily life and how these views impact on management. The aim of this study was to describe experiences of daily life, with particular focus on thoughts, feelings and management of adolescents with asthma.METHODS: In this qualitative study, data were obtained from 10 interviews with adolescents (aged 16-18 years) with asthma recruited from the Swedish population-based prospective birth cohort, BAMSE. Data were analysed through Systematic Text Condensation.RESULTS: Experiences of daily life among adolescents with asthma were defined in four categories: Insight and understanding; Asthma not the focus of daily life; Being acknowledged and, Being affected by asthma symptoms. The adolescents had developed an insight into and understanding of their disease, but did not want asthma to be the focus of their daily lives. The adolescents wanted their asthma to be acknowledged, but not to the point that they were defined by their asthma. They reported having many asthma symptoms, especially during physical activity, but also described a desire to feel healthy, "normal" and like their peers.CONCLUSIONS: Having asthma in adolescence involves several struggles with ambivalence between adapting socially, feeling healthy and managing one's asthma.IMPLICATIONS IN CLINICAL PRACTICE: The provision of person-centred care may be one way to handle the ambivalence among adolescents with asthma and thereby help them to manage their asthma.
