✦ Synopsis
Determination of the absolute configuration of alkaloids from Equisetum sp.,e.g. (+)‐palustrin, palustridin ((+)‐hydrochloride), and (−)‐dihydropalustramic acid and derivatives
The absolute configuration of the title alkaloids has been determined using chiroptical methods (ORD., superposition of CD. values of appropriate models and a modified Horeau method). (+)‐Palustrin is (13R, 17 S, 1′S)‐17‐(1‐hydroxypropyl)‐1,5,10‐triazabicyclo [11.4.0]heptadec‐15‐en‐11‐on.
