Synthetic organic chemistry based on small ring compounds.
Small ring systems are important topics in both organic and inorganic chemistry, and draw considerable attention from both theoretical and preparative perspectives. This review intends to summarize the studies, focusing on the preparative aspects, that have been carried out in our laboratory. Namely, synthesis of (+)- and (-)-alpha-cuparenone, (+)-ipomeamarone, (+)-epiipomeamarone, (-)-ngaione,...
متن کاملNew acetylenic norlignan compounds from rhizomes of Curculigo crassifolia.
Two pairs of diastereoisomeric acetylenic norlignan compounds with PhCH(OR(1))CH(OR(2))CH(2)C triple bond CPh skeleta: (1R, 2R)-1-O-methylnyasicoside (1) and (1S, 2R)-1-O-methylnyasicoside (2), and (1R, 2R)-crassifogenin D (3) and (1S, 2R)- crassifogenin D (4), were isolated from the ethanolic extract of rhizomes of Curculigo crassifolia. Compounds 3 and 4 are new and their structures were eluc...
متن کاملAcetylene Chemistry: “acetylenic Tree” in Organic Synthesis on the Eve of Xxi Century
В первой статье, посвященной химии ацетилена [1], были рассмотрены строение и реакционная способность алкинов, включая строение и реакции π -комплексов алкинов с переходными металлами. Высокая реакционная способность С ≡ Си ≡ С–Н-связей в алкинах делает их участниками разнообразнейших реакций, составляющих основу раздела органической синтетической и промышленной химии, который называется “химия...
متن کاملFuran ring opening-pyrrole ring closure: a new synthetic route to aryl(heteroaryl)-annulated pyrrolo[1,2-a][1,4]diazepines.
A method of synthesis of pyrrolo[1,2-a][1,4]benzodiazepines is described. This method is based on the recyclization of N-(furfuryl)anthranilamides under treatment with an aq. HCl/AcOH system and allows one to form both diazepine and pyrrole rings in one step. The reaction proceeds via furan ring opening into a diketone moiety followed by consecutive interaction of the NH(2)-group with both carb...
متن کاملNew synthetic transformations via organoboron compounds
It was previously reported that the palladium-catalyzed cross-coupling reaction of 1-alkenylboron compounds with various vinylic or aryl halides in the presence of base provides the corresponding coupling products in high yields, stereoand regioselectively. The recent progress of such reactions, including the reaction of sterically hindered arylboronic acids with sterically hindered haloarenes,...
