Area of Science:

  • Organic Chemistry
  • Natural Product Synthesis

Background:

  • Homo-monoterpenes are a class of natural products with diverse biological activities.
  • Robinlin is a novel homo-monoterpene whose synthesis and bioactivity were previously uncharacterized.

Purpose of the Study:

  • To achieve the first total synthesis of (+/-)-robinlin.
  • To evaluate the bioactivity of (+/-)-robinlin using the brine shrimp lethality test.

Main Methods:

  • The synthesis commenced from 3-isobutyloxy-2,6,6-trimethyl-2-cyclohexen-1-one.
  • Standard organic synthesis techniques were employed.

Main Results:

  • The first successful synthesis of (+/-)-robinlin was accomplished.
  • (+/-)-Robinlin exhibited strong bioactivity in the brine shrimp lethality assay.
