产品详情(用途,包装等) Longifolene is the common (or trivial) chemical name of a naturally occurring, oily liquid hydrocarbon found primarily in the high-boiling fraction of certain pine resins. The name is derived from that of a pine species from which the compound was isolated, Pinus longifolia (obsolete name for Pinus roxburghii Sarg.) Chemically, longifolene is a tricyclic sesquiterpene. This molecule is chiral, and the enantiomer commonly found in pines and other higher plants exhibits a positive optical rotation of +42.73°. The other enantiomer (optical rotation ?42.73°) is found in small amounts in certain fungi and liverworts. Longifolene is used in organic synthesis for the preparation of dilongifolylborane, a chiral hydroborating agent. |
