Исходный трет-бутилоксикарбониллейцилметоксипролин был получен, как и синтезированный ранее трет-бутилоксикарбонилпролилметоксилейцин, карбодиимидным методом. Установлено, что циклизация метилового эфира L-лейцил-L-пролина в целевой дикетопиперазин протекает при более низкой температуре, чем циклизация метилового эфира L-пролил-L-лейцина.</p></abstract><trans-abstract xml:lang="en"><p>3-Isobutylhexahydropyrrolo[1,2-a]pyrazine-1,4-dione, [cyclo(prolyl-leucyl)], which has a wide range of biological effects, was obtained by thermolysis both the L-prolyl-L-leucine methyl ester and the methyl ester L-leucyl-L-proline, for the synthesis of which the removal of tert-butyloxycarbonyl amino protecting groups in tert-butyloxycarbonylprolyl-leucine methyl ester and tert-butyloxycarbonylleucyl-proline methyl ester under the action of a methanolic solution of hydrogen chloride and the treatment of the resulting of methyl esters hydrochlorides L-prolyl-L-leucine and L-leucyl-L-proline with an equimolar amount of triethylamine were used. The starting tert-butyloxycarbonylleucyl-proline methyl ester was prepared like the previously synthesized tert-butyloxycarbonylprolyl-leucine methyl ester by the carbodiimide method. It was found that the cyclization of the methyl ester of L-leucyl-L-proline into the desired diketopiperazine proceeds at a lower temperature than the cyclization of the methyl ester of L-prolyl-L-leucine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цикло(пролил-лейцил)</kwd><kwd>2</kwd><kwd>5-дикетопиперазины</kwd><kwd>метиловые эфиры дипептидов</kwd><kwd>трет-бутилоксикарбонильные производные дипептидов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cyclo(prolyl-leucyl)</kwd><kwd>2</kwd><kwd>5-diketopiperazines</kwd><kwd>methyl esters of dipeptides</kwd><kwd>tert-butyloxycarbonyl derivatives of dipeptides</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Quantification of cyclic dipeptides from cultures of Lactobacillus brevis R2Δ by HRGC/MS using stable isotope dilution assay / C.
