Abstract

4-(3′(R)-hydroxybutyl)-3,5,5 Trimethyl-cyclohex-2-en-1-one 5-benzofuran Carboxylic Acid-6-formylmethyl Ester Morinda Citrifolia Rubiaceae
The leaves of Morinda citrifolia, Linn. afforded a new benzofuran and a bis-nor-isoprenoid, blumenol C, hitherto unreported from this source. The structures of these have been elucidated as 5-benzofuran carboxylic acid-6-formyl methyl ester (1) and 4-(3′(R)-hydroxybutyl)-3,5,5, trimethyl-cyclohex-2-en-1-one (2) respectively through spectroscopic studies. The NMR data (including 1D, 2D techniques) and stereochemistry at C-3′ of Compound 2 is also being reported for the first time.
