The present invention relates to novel compounds useful as fragrance materials which have the structure ##STR1## wherein the dashed line may be either a carbon-carbon single bond or a carbon-carbon double bond; R.sub.1, R.sub.2 and R.sub.3 are each the same or different and each represents hydrogen or methyl; and X is halogen. The invention also provides methods of preparing these compounds from readily available cyclohexene derivatives and fragrance compositions which include the compounds.
本发明涉及一种新型化合物,其结构为## STR1 ##,可用作
香料材料,其中虚线可以是碳-碳单键或碳-碳双键; R1,R2和R3均相同或不同,每个代表氢或甲基; X是卤素。本发明还提供了从易于获取的
环己烯衍
