✦ Synopsis

Isolation, Structure, and Synthesis of Chenopodanol and the Absolute Configuration of Chenopodene and Chenopodanol. -Chenopodanol is isolated from the liverwort Marchantia chenopoda and its structure is determined by spectroscopy as well as by total synthesis starting from the chiral keto ester (I). The results obtained from (+)-(IV) point to the fact that natural chenopodanol must be revised to structure (-)-(IV). Methylation of diastereomer (V) affords chenopodene (VI) in optically active form. -(TORI,
