The Thre-Component Condensation of Monoterpenes with Formaldehyde and Cyclohexane-1,3-dione. A Simple Route to Polyketide Terpenes

HETEROCYCLES, 1994
The framework of polyketide terpenes was obtained by the title tandem reaction which was carried out in one-pot under optimized conditions. Even tetrasubstituted olefins react, sterically hindered octahydro- naphthalene (6) giving tetracyclic propellane (7)

Gas-phase products and secondary aerosol yields from the ozonolysis of ten different terpenes [PDF]

, 2006
The ozonolyses of six monoterpenes (α-pinene, β-pinene, 3-carene, terpinolene, α-terpinene, and myrcene), two sesquiterpenes (α-humulene and β-caryophyllene), and two oxygenated terpenes (methyl chavicol and linalool) were conducted individually in ...

The kinetics of the gas-phase reactions of selected monoterpenes and cyclo-alkenes with ozone and the NO3 radical [PDF]

, 2013
The relative rate method has been used to measure the room-temperature rate constants for the gasphase reactions of ozone and NO3 with selected monoterpenes and cyclo-alkenes with structural similarities to monoterpenes.

Observation of gaseous and particulate products of monoterpene oxidation in forest atmospheres [PDF]

, 1999
Atmospheric oxidation of biogenic hydrocarbons, such as monoterpenes, is estimated to be a significant source of global aerosol. Whereas laboratory studies have established that photochemical oxidation of monoterpenes leads to aerosol formation, there ...

Photooxidation of 2-methyl-3-buten-2-ol (MBO) as a potential source of secondary organic aerosol [PDF]

, 2009
2-Methyl-3-buten-2-ol (MBO) is an important biogenic hydrocarbon emitted in large quantities by pine forests. Atmospheric photooxidation of MBO is known to lead to oxygenated compounds, such as glycolaldehyde, which is the precursor to glyoxal.
