Honors Theses

This work presents the progress made towards synthesizing 2-oxo-16-(3', 4'methylenedioxyphenyl)-trans-15-hexadecene, an antimycobacterial compound that was originally isolated from the leaves of Piper Sanctum. The hydrocarbon chain of the molecule was synthesized first by opening a 15-pentadecanolactone ring by means of HI, and performing an E2 elimination reaction on the molecule followed by an organolithium reaction with CH3Li. Hexadec-15-en-2-one that was afforded this way was later reacted with 5-bromobenzo[d][1,3]dioxole following the appropriate Heck reaction protocol that allows for the formation of a palladium catalyzed carbon-carbon bond.

The modes of action of 2-oxo-16-(3', 4'-methylenedioxyphenyl)-trans-15hexadecene are comparable to the ones of rifampicin, a …
