Abstract
Three previously undescribed dihydronaphthalenones, 7-hydroxycatalponol, (4S)-3,4-dihydro-4-hydroxy-2-[(2R)-2,3-dihydroxy-3-methylbutylidene]naphthalen-1(2H)-one, and (6S)-5,6-dihydro-6-hydroxy-2,2-dimethyl-2H-benzo[h]chromen-4(3H)-one and one phthalide, (±)-3-(5-hydroxy-5-methyl-2-oxohex-3-en-1-yl)isobenzofuran-1(3H)-one, were isolated from the wood of Catalpa ovata G. Don (Bignoniaceae), together with six known compounds. The structures of the previously undescribed compounds were elucidated by interpretation of 1D and 2D NMR data. The absolute configurations of the dihydronaphthalenones were deduced by analysis of the ECD data and application of Mosher ester methodology. All isolates were investigated for their cytoprotective effects against hydrogen peroxide (H2O2)-induced oxidative damage in HepG2 cells. Moreover, the mRNA expression levels of antioxidant enzymes such as heme oxygenase-1 (HO-1) and NAD(P)H:quinine oxidoreductase 1 (NQO1) in HepG2 cells were examined by RT-PCR analysis. As a result, catalponol and epi-catalponol showed antioxidant activities via directly scavenging of intracellular ROS and inducing the antioxidant enzymes in vitro.

Abstract
Complementary to enzymatic methods, catalytic enantioselective desymmetrisation of meso-diols (EDMD) by small molecule catalysts has emerged as a powerful tool that provides highly enantioenriched materials of considerable value in organic synthesis. This review traces the evolution of easily accessible catalysts used in the EDMD and compares their performance with the existing enzymatic methods.
