Stereocontrolled total synthesis of (±)hydroxy patchouli alcohol and the corresponding (±)-carboxylic acid, metabolites of patchouli alcohol, and (±)-norpatchoulenol
The first total synthesis of (±)-hydroxy patchoulialcohol (3) and the corresponding (±)-carboxylic acid 4, the biooxidation products of patchoulialcohol (2) has been achieved. (±)-Norpatchoulenol (1) has also been synthesized by the biogenetic route via 3 and 4.
