A biomimetic transformation of p-menthene glucosides into aromatic monoterpenoids that alluded to mechanisms for essential oil metabolism, which lines up with the precepts of molecular economy, is described. Acid treatment of (-)-(3 S,4 S,6 R)-3,6-dihydroxy-1-menthene 3- O-β-d-glucopyranoside (1) and (-)-(3 S,4 R,5 R,6 S)-3,5,6-trihydroxy-1-menthene 3- O-β-d-glucopyranoside (2), from Ageratina glabrata
描述了对-薄荷烯糖苷向芳香单萜类化合物的仿生转化,这暗示了精油代谢的机制,这与分子经济的规律相吻合。(-)-(3 S,4 S,6 R)-3,6-二羟基-1-薄荷烯3-O-β-d-吡喃葡萄糖苷(1)和(-)-(3 S,4 R来自姬松茸的1,5 R,6 S)-3,5,6-三羟基-1-薄荷烯3-O-β-d-吡喃葡萄糖苷(2)产生对伞花烃(7)和香芹酚(9)。稳定的氧化中间体(+)-(3 S,4 S,6 R)-3,6-二羟基-1-薄荷烯(3),(+)-(1 S,4 S,6 R)-1,6 -二羟基-2-薄荷烯(4),(+)-(1 R,4 S,6 R)-1,6-二羟基-2-薄荷烯(5),(+)-(4 S,6 R)- yabunikkeol(6),(+)-(4 S)-香豆丙酮(8),(+)-(1 S,4 S,5 R,6 R)-1,5,6-三羟基-2-薄荷烯(15 ),(+)-(1 R,4 S,5 R,6
