Data from: Ce(OTf)3-catalyzed asymmetric 6pi cyclization of triaryldivinyl Ketones
Abstract
The rare-earth Ce(OTf)3-catalyzed asymmetric 6pi cyclization of triaryldivinyl ketones is realized, affording methyl (R,E)-1-aryl-2-arylmethylidene-3-hydroxy-1,4-dihydronaphthalene-2-carboxylates in moderate to good yields with good to excellent enantioselectivities. The reaction provided a new strategy for the construction of optically active 3-hydroxy-1,4-dihydronaphthalene-2-carboxylic acid derivatives. The original NMR data (FID files and mnova files) of both starting materials [4-(3,4-dimethoxyphenyl)-5-aryl-3-oxo-2-((Z)-4-arylmethylidene)pent-4-enoates] and products [(R,E)-1-aryl-2-arylmethylidene-3-hydroxy-1,4-dihydronaphthalene-2-carboxylates) are provided and the files can be opened with MestReNova software.
Each folder of NMR FID files contains subfolders on different NMR FID and mnova files.
