A novel and highly efficient route to new indanoyl isoleucine conjugates is described, which allows a wide range of substituents to be attached to the 6-position of the indanoyl moiety. We report the synthesis of conjugates with methyl, methoxy, propoxy, allyloxy, pentoxy, and 2-(2-methoxy-ethoxy)-ethoxy 6-position substituents. Preliminary biological activities of the novel compounds with significantly enhanced water solubility were determined using the Lima bean (Phaseolus lunatus) volatile bioassay. The compounds induce variable volatile patterns, and structure-activity relationships show an ability to differentially induce separate pathways leading to secondary metabolites.
