Abstract

The epigeal part of the plantLagochilus hirsutissimus has yielded a new diterpenoid lactone — lagohirsidin, C22H34O5, mp 144–145°C, [α] D 22 − 17.5° (c 1; ethanol). Reduction with LiAlH4 has yielded a diol C22H38O5, mp 165–166°C [α] D 20 −1.2 (c 0.6; ethanol). Acid hydrolysis of the diol has led to the formation of lagochilin, C20H36O5, mp 167–168°C, [α] D 20 −3.9° (c 1; ethanol). The synthesis of lagohirsidin from lagochilin has been effected.
