✦ Synopsis
Isolation and NMR‐Spectroscopic Investigations of (−)‐1‐O‐Benzyl‐β‐D‐primveroside from Green Fruits of Prunus laurocerasus
The TLC of the acetylated aqueous extracts of the green fruits of Prunus laurocerasus reveals two spots corresponding to pentaacetyl‐glucopyranose and hexaacetyl‐1‐O‐benzyl‐β‐D‐primveroside (2), which can be quantitatively separated by flash chromatography. Saponification of 2 yields the free 1‐O‐benzyl‐β‐D‐primveroside (1) which affords D‐primverose (3) upon hydrogenolysis. The direct hydrogenolysis of 2 yields hexaacetyl‐β‐D‐primverose (4). The structures of compounds 1–4 have been verified by NMR spectroscopy.
