Abstract:
The first total synthesis of louisianin A, 4-allyl-6,7-dihydro-1-hydroxycyclopenta[c]pyridin-5-one, is achieved from 2-chloro-4-cyanopyridine 5 via seven steps in an overall 24% yield. The key step is a cyclization-decarboxylation sequence toward the formation of a cyclopentenone ring.

Strong bases like NaOH or KOH deprotonate the phthalimide to form the corresponding anion, which acts as a nucleophile. Further, the anion attacks an...
Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
