Tannins and related compounds 29. 7 new methyl derivatives of flavan 3 ols and a 1 3 diarylpropan 2 ol from cinnamomum cassia cinnamomum obtusifolium and lindera umbellata var membranacea



Chemical and Pharmaceutical Bulletin 33(6): 2281-2286



Seven new methyl derivatives of flavan-3-ols (compounds 1-7) and one 1,3-diarylpropan-2-ol (compound 8) were isolated from 3 Lauraceous plants 1, and 3-7 from Cinnamomum cassia, 1, 3 and 4 from C. obtusifolium, and 1-4 and 8 from Lindera umbellata var. membranacea. Their structures were characterized mainly by 1H-NMR examination combined with nuclear Overhauser effect (NOE) experiments as the 3'-O-methylate (1), 3',4'-di-O-methylate (2) 5,3'-di-O-methylate (3) and 5,7,3'-tri-O-methylate (4) of (-)-epicatechin, the 4'-O-methylate (5), 7,4'-di-O-methylate (6) and 5,7,4'-tri-O-methylate (7) of (+)-catechin, and 1-(4',6'-dihydroxy-2'-methoxyphenyl)-3-(4"-Hydroxy-3"-methoxyphenyl)-propan-2-ol (8).
