General description

(+)-α-Pinene is a monoterpenoid compound mainly found in Pinus species.

Application

(+)-α-Pinene may be used as precursors to prepare primary, secondary and tertiary γ-amino alcohols and 1,3-diamines, which can be used as chiral catalysts for the addition of diethylzinc to aromatic aldehydes, resulting in chiral 1-aryl-1-propanols with high enantioselectivity.
Employed in the preparation of chiral hydroboration reagents.

For centuries, herbs have been used by traditional therapists around the world to treat gastrointestinal tract disorders, such as gastritis. We hypothesized that the anti-Helicobacter pylori properties of phytoncide, which is extracted from pinecone waste, would facilitate use as a

Cognitive capacities afford contingent associations between sensory information and behavioral responses. We studied this problem using an olfactory delayed match to sample task whereby a sample odor specifies the association between a subsequent test odor and rewarding action. Multi-neuron recordings
