Abstract Papers on medical subjects have been published since the first issue of the journal Prilozi in 1969, totalling a number of of 957 (nine hundred and fifty seven) papers have been published in Prilozi. Two hundred and twenty nine cover subjects on natural sciences and mathematics, and 728 (seven hundred and twenty eight) subjects on medical sciences. So far, 2017 No. XXXVIII-2, 622 (six hundred and twenty two) papers published in Prilozi are in Pubmed. Prilozi is published three times a year and it is covered by the following services: Baidu Scholar, Case, Celdes, CNKI Scholar (China National Knowledge Infrastructure), CNPIEC, DOAJ (Directory of Open Access Journals), EBSCO (relevant databases), EBSCO Discovery Service, Elsevier – SCOPUS, Google Scholar, J-Gate, JournalTOCs, KESLI-NDSL (Korean National Discovery for Science Leaders), Naviga (Softweco), Primo Central (ExLibris), Publons, PubMed, ReadCube, ResearchGate, SCImago (SJR), Summon (Serials Solutions/ProQuest), TDNet, Ulrich’s Periodicals Directory/ulrichsweb WanFang Data, WorldCat (OCLC).

The article is dedicated to Pavel A. Stunzhas, a highly qualified specialist in the field of Marine Hydrochemistry, a graduate from the Moscow Institute of Physics and Technology. He was a Senior Researcher at the Laboratory of Biohydrochemistry at the Shirshov Institute of Oceanology Russian Academy of Sciences, PhD on Physics and Mathematics sciences. July 2, 2020, he celebrated his 80th birthday, but by the will of fate and COVD'19, he suddenly passed away on October 29 of this year. He worked at the Institute of Oceanology for 46 years – from the first to the last days of his life.

In the article we seek to address questions regarding the interest of graduates of a degree course in Natural Sciences and Mathematics in relation to the teaching career in basic education. The course enables its graduates to work in the subjects Science and Mathematics in the final years of elementary school and Mathematics, Physics and Chemistry in high school. Our intention is to identify and reflect on the perceptions of these graduates about teaching, highlighting with this inherent aspects to the exercise of this profession in basic education. From the application of questionnaires to graduates of this course, we produced data regarding their performance in basic education, which enabled us to reflect on the national scenario in relation to the exercise of this profession. We could observe that the majority of the students participating in the research are not working in basic education and that the current scenario of devaluation of the teaching career exerts a significant influence in the decision making process of choosing or not the teacher profession for professional performance after graduation.

Were developed new and practical synthesis of (Z)-7-dodecene-1-yl acetate and (E)-9-dodecene-1-yl acetate. The routes involve, as the key step, the use of the mercury derivative of the terminal-alkyne w-functionalised as intermediate. The synthesis of (Z)-7-dodecene-1-yl acetate was based on a C6+C2=C8 and C8+C4=C12 coupling scheme, starting from 1,6-hexane-diol. The first coupling reaction took place between 1-tert-butoxy-6-bromo-hexane and lithium acetylide-ethylendiamine complex obtaining 1-tert-butoxy-oct-7-yne, which is transformed in di[tert-butoxy-oct-7-yne]mercury. The mercury derivative was directly lithiated and then alkylated with 1-bromobutane obtaining 1-tert-butoxy-dodec-7-yne. After acetylation and reduction with lithium aluminium hydride of 7-dodecyne-1-yl acetate gave (Z)-7-dodecene-1-yl acetate with 96 % purity. The synthesis of (E)-9-dodecene-1-yl acetate was based on a C8+C2=C10 and C10+C2=C12 coupling scheme, starting from 1,8-octane-diol. The first coupling reaction took place between 1-tert-butoxy-8-bromo-octane and lithium acetylide-ethylendiamine complex obtaining 1-tert-butoxy-dec-9-yne, which is transformed in di[tert-butoxy-dec-9-yne]mercury. The mercury derivative was directly lithiated and then alkylated with 1-bromoethane obtaining 1-tert-butoxy-dodec-9-yne. After reduction with lithium aluminium hydride of 1-tert-butoxy-(E)-9-dodecene and acetylation was obtained (E)-9-dodecene-1-yl acetate with 97 % purity.

4-Chloromethyl-s-hydrindacene (VIIa) was transformed via the malonic acid derivatives VIIIa and IXa to the acid Xb which afforded in four steps the homological acid Xc. Reactions of chlorides of both acids (XIbc ) with dimethylamine, 1-methylpiperazine and 1-(2-hydroxyethyl)piperazine led to the amides XIIbc-XIVbc which were reduced with lithium aluminium hydride to the title compounds IVcd-VIcd. The amines obtained show central neuroleptic effects only in subtoxic doses; they are also potent local anaesthetics and have significant spasmolytic activity of the neurotropic as well as musculotropic type.

(Arylthio)benzoic acids IIa - IIe and VIb - VId were transformed via the acid chlorides to the N,N-dimethylamides which were reduced either with diborane "in situ" or with lithium aluminium hydride to N,N-dimethyl-(arylthio)benzylamines Ia - Ie and Vb - Vd. Leuckart reaction of the aldehydes IX and X with dimethylformamide and formic acid afforded directly the amines Va and Ve. Demethylation of the methoxy compounds Ia and Ve with hydrobromic acid resulted in the phenolic amines If and Vf. The most interesting N,N-dimethyl-4-(phenylthio)benzylamine (Va) hydrochloride showed affinity to cholinergic and 5-HT2 serotonin receptors in the rat brain and some properties considered indicative of antidepressant activity (inhibition of serotonin re-uptake in the brain and potentiation of yohimbine toxicity in mice).
