Intraspecific variation in essential oil composition of Eremophila longifolia F. Muell. (Myoporaceae): evidence for three chemotypes.
Volatile oils of Eremophila longifolia F. Muell leaves were obtained by hydrodistillation and analysed using GC-MS, enabling classification of three chemotypes in this species. Expand
Boron trifluoride etherate in organic synthesis
The innumerable applications of boron trifluoride etherate of boron trifluoride etherate in organic synthesi1,2 encouraged us to write a micro review on this reagent. The commercially available boronExpand

Enantioselective synthesis of both enantiomers of γ-ionone, γ-damascone, karahana lactone and karahana ether
Abstract A straightforward enantioselective synthesis of both enantiomers of the title compounds is described starting from enantiopure methyl (2 S ,6 R )- or (2 R ,6 S )- cisExpand
Straightforward Enantioselective Synthesis of Both Enantiomers of Karahana Lactone Using a Domino Ring-Closure Sequence
Abstract A straightforward enantioselective synthesis of both enantiomers of karahana lactone is described starting from enantiopure (R) or (S)-4-hydroxy-3-methyl-cyclohex-2-en-1-one. The key step ofExpand


Favorskii rearrangement of the pulegone epoxides
Abstract The pulegone epoxide I, with sodium ethoxide in ethanol, gives as the major product, the ‘puleganolic’ acid III; similarly epoxide V gives the ‘puleganolic’ acid VII with the puleganolideExpand
