    摘要： The present invention relates to the field of perfumery. More particularly, it concerns a composition of matter comprising a compound of formula (I) as defined below wherein the weight ratio of the cis-diastereoisomers to the trans-diastereoisomers is comprised in the range between 90:10 and 99.5:0.5 and comprising at least 10% w/w of cis-(1S,2R) diastereoisomer. Said composition of matter is a useful perfumery ingredient, and therefore the present invention comprises the invention composition of matter as part of a perfuming composition or of a perfuming consumer product.
