Abstract
The aerial parrs of Cluytia richardiana yielded two new labdane-type d iterpenoids, named cluytene A [3] and cluytene B [4]. The structural a ssignments and relative stereochemistry of both compounds were establi shed from 2D nmr spectral data and by X-ray crystallographic analysis. Furthermore, cluytene B [4] was found to undergo a peculiar eliminati on reaction when treated with 1,5-diazabicyclo[5.4.0]undec-5-ene to gi ve the highly conjugated produce 5.
