In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called A photoisomerization-coupled asymmetric Stetter reaction: application to the total synthesis of three diastereomers of (-)-cephalimysin A, published in 2013, which mentions a compound: 1214711-48-4, Name is (5aS,10bR)-2-(2,4,6-Trichlorophenyl)-4,5a,6,10b-tetrahydro-2H-indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazin-11-ium tetrafluoroborate, Molecular C18H13BCl3F4N3O, COA of Formula: C18H13BCl3F4N3O.
The total synthesis of 8-epi-cephalimysin A, 8,9-epi-cephalimysin A and 9-epi-(-)-cephalimysin A is described. This catalytic enantioselective synthesis takes advantage of a novel tandem photoisomerization/Stetter reaction. The approach provides rapid access to the desired spirofuranone lactam core in good yield and excellent enantioselectivity. A late stage oxidation strategy allows for flexible access to three of the four diastereomers of cephalimysin A. Access to the epimers provides further support for the correction of the initially proposed relative stereochem. of cephalimysin A. The title compounds thus formed included 8-epi-cephalimycin A (I) and related substances, (5S,8R,9R)-8-Benzoyl-2-(3E)-3-hexen-1-yl-9-hydroxy-8-methoxy-3-methyl-1-oxa-7-azaspiro[4.4]non-2-ene-4,6-dione cephalimysin A. The synthesis of the target compounds was achieved using (5aR,10bS)-5a,10b-dihydro-2-(2,3,4,5,6-pentafluorophenyl)-4H,6H-indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazinium, tetrafluoroborate(1-) as catalyst.
From this literature《A photoisomerization-coupled asymmetric Stetter reaction: application to the total synthesis of three diastereomers of (-)-cephalimysin A》,we know some information about this compound(1214711-48-4)COA of Formula: C18H13BCl3F4N3O, but this is not all information, there are many literatures related to this compound(1214711-48-4).
