The resulting 2-chlorothioxantone is reacted as a carbonyl component with either 3-dimethylaminopropylmagnesiumbromide ( see Engelhardt above ), or with allylmagnesiumbromide, giving the corresponding tertiary alcohols "'8 "', and "'9 " '.

"' 4-Hydroxy-4-methylpentanoic acid "'( "'UMB68 "') is a tertiary alcohol, similar in structure to the drug GHB . The molecule has been synthesized and tested on animals in order to further research the effects of GHB . UMB68 has been shown to bind selectively to the GHB receptor ligand in binding assays, yet does not bind to GABAergic receptors.

It has recently been shown ( Keeling, " et al . ", 2011 ) that the orthologous gene in Norway spruce ( " Picea abies " ) does not produce abietadiene directly, but instead produces a thermally unstable allylic tertiary alcohol 13-hydroxy-8 ( 14 )-abietene, which readily dehydrates to abietadiene, levopimaradiene, palustradiene, and neoabietadiene, when analyzed by the commonly used gas chromatography.
