Grasshopper ketone synthesis

Scheme 18.13 Synthesis of the grasshopper ketone (34) according to Eugster and co-workers [46d] (DIBAH = diisobutylaluminum hydride). Scheme 18.13 Synthesis of the grasshopper ketone (34) according to Eugster and co-workers [46d] (DIBAH = diisobutylaluminum hydride).
A representative allenic carotenoid is mimulaxanthin (202), a symmetrical structure with allenic end groups. For the total synthesis of mimulaxanthin (202), the most suitable candidate starting compound is the grasshopper ketone (11a) which has been synthesized by several groups [7-13]. [Pg.204]

The large, flightless grasshopper, Romalea microptera excretes a novel sesquiterpenoid allenic ketone in its defensive secretionsJ Meinwald and Hendry confirmed the proposed structure and stereochemistry of this ant-repellant substance by stereospecific synthesis from isophorone. [Pg.121]
