The present invention relates to trans isomers of formula (I)
in the form of any one of its stereoisomers or a mixture thereof, and wherein the bold and hatched lines indicate a relative or absolute configuration; and one dotted line represents a carbon-carbon single bond and the other a carbon-carbon double bond;
and their uses as perfuming ingredients (e.g. to impart vetiver/rooty notes), e.g. in consumer products.
Described herein is a process including isomerizing the β position of a β-trisubstituted C3-C70 carbonyl compound.
本文描述的工艺包括对 β-三取代 C3-C70 羰基化合物的 β 位进行异构化。

The outcome of oxidative ring expansion/cyclisation of cyclopropanes with a mixed Fe(III)/Cu(II) system was found to be dependent on the mode of cyclisation. When 6-exo cyclisation was attempted unusual products resulting from oxidation of ring opened primary radicals were obtained. (C) 2000 Elsevier Science Ltd. All rights reserved.
