Diterpene synthases and methods of their use are described herein.

An organic electroluminescence device includes a first electrode, a hole transport region on the first electrode, an emission layer on the hole transport region, an electron transport region on the emission layer, and a second electrode on the electron transport region. The hole transport region includes a monoamine compound represented by the following Formula 1:

##STR00001##

Disclosed are methods of preparing unsaturated carbocyclic compounds through dehydrogenation of corresponding saturated carbocyclic compounds.

The present invention relates to a process for preparing 1-[(1R,4R/S,8S)-10,10-dimethyl-7-methylene-4-bicyclo[6.2.0]decanyl]ethanone.

The present invention relates to compounds and their uses, in particular, compounds in the form of prodrugs that pro mote transport of a pharmaceutical agent to the lymphatic system and subsequently enhance release of the parent drug.

The present disclosure relates to methods of carbon-carbon bond fragmentation.

The present invention relates to 1-(7,10,10-trimethyl-4-bicyclo[6.2.0]decanyl)ethanone, the use of 1-(7,10,10-trimethyl-4-bicyclo[6.2.0]decanyl)ethanone as a fragrance or as flavor, to a method for imparting or modifying a scent or a flavor to a composition by including said compound into such composition, to a fragrance containing composition and/or a fragrance material containing said compound and to a process for preparing 1-(7,10,10-trimethyl-4-bicyclo[6.2.0]decanyl)ethanone.

A resin compound has a structure represented by a chemical formula (I): ##STR00001## In the chemical formula (I), each R.sup.1 independently represents a C.sub.1-C.sub.20 alkylene group or a C.sub.7-C.sub.40 alkylarylene group, and R.sup.1 are the same or different from each other; n independently represents an integer of 1-4; each R.sup.2 independently represents a C.sub.1-C.sub.20 alkyl group or a C.sub.2-C.sub.20 terminal alkenyl group, and R.sup.2 are the same or different from each other. When at least one of R.sup.1 represents a C.sub.1-C.sub.20 alkylene group, at least one of R.sup.2 is a C.sub.2-C.sub.20 terminal alkenyl group.

In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein is versatile polyene cyclization strategy that exploits conjugated -ionyl derivatives. Photomediated disruption of the extended -system within these chromophores unveils a contra-thermodynamic polyene that engages in a Heck-type cyclization to afford [4.4.1]-propellanes. The connectivity of overbred polycycles generated from this process is controlled by the position of the requisite C-Halide bond. Thus, compared to conventional biomimetic polyene cyclization, this approach allows for complete control of regiochemistry and facilitates incorporation of both electron-rich and electron-deficient (hetero)aryl groups. This strategy was successfully applied to the total synthesis of abietanes such as, for example, taxodione and salviasperanol, two isomeric abietane-type diterpenes that previously could not be prepared along the same synthetic pathway.

Compounds of formula (I) can modulate the activity of autotaxin (ATX).
