ENANTIOMERIC COMPOSITION OF MONOTERPENE HYDROCARBONS FROM THE LIVERWORT CONOCEPHALUM CONICUM

Volatiles from the essential oil of the liverwort Conocephalum conicum were analysed.The chirality of the monoterpene hydrocarbons was studied by two-dimensional gas chromatography.All compounds except β-phellandrene showed high optical purity.For the identification of enantiomers, (+)-β-phellandrene and (-)-α-thujene were prepared from (+)-limonene and (+)-sabinene, respectively.Key Word Index: Conocephalum conicum; Hepaticae; liverwort; monoterpene hydrocarbons; (+)-β-phellandrene; (-)-α-thujene; chiral composition

High-Throughput Synthesis of (S)-α-Phellandrene through Three-Step Sequential Continuous-Flow Reactions

The combination of continuous-flow processing with heterogeneous catalysts allows for efficient, sustainable, multistep synthesis. Here, we report the continuous-flow synthesis of a valuable terpene product, phellandrene, from a readily available natural feedstock. The protocol consists of selective hydrogenation using a highly active and stable supported platinum catalyst, dehydrative hydrazone formation, followed by the Shapiro reaction. Appropriate design of the reactor allowed for high productivity and space-time yield. Phellandrene was synthesized on a 30-g scale over 6 h, giving high yields, purity, and productivity.

Triphenylpyrylium tetrafluoroborate-sensitized photochemistry of the terpenes sabinene, α-phellandrene, and α- and γ-terpinene

The triphenypyrylium tetrafluoroborate (TPT)-sensitized reactions of several terpene donor molecules, including sabinene (1), α-phellandrene (4), α-terpinene (5) and γ-terpinene (6) give rise to significantly different products than reactions induced by other electron-transfer sensitizers, such as 1,4-dicyanobenzene (DCB). The divergent reactions require decidedly different key intermediates; the products obtained with TPT can be explained by dissociative recombination of the intermediate radical-radical cation pair in the triplet state, generating donor-derived biradicals.
