Organocatalytic Reductive Propargylation: Scope and Applications

An amino acid-catalyzed three-component reductive coupling protocol has been developed for the selective high-yielding synthesis of nearly fifty examples of propargylated cyclic/acyclic systems from the various propargyl aldehydes, cyclic/acyclic CH acids, and Hantzsch ester under ambient conditions. It is an economical, efficient, catalytic, metal-free protocol for the quick gram-scale synthesis of propargylated cyclic/acyclic compounds, and many of these coupling compounds were purified by a simple precipitation-filtration technique instead of column chromatography. Functionally rich propargylated cyclic-1,3-diketones were specifically transformed into dihydropyrans found in natural products and drugs through an annulative etherification reaction by using Lewis-acid (AgOTf) catalysis. Further, we developed the C-methylation reactions on propargylated cyclic-1,3-diketones, which are prolific synthons in natural products and medicinal chemistry.

Asymmetric Synthesis of Carbocyclic Propellanes

A modular synthesis of functionalized carbocyclic propellanes was developed. Formation of the first of two quaternary bridgehead centers has been achieved by desymmetrization of prostereogenic ketones by either Hajos-Parrish-Eder-Sauer-Wiechert-type processes or Werner’s catalytic asymmetric Wittig reaction. The obtained bicyclic enones were subjected to conjugate additions upon which the remaining ring was formed by olefin metathesis. All bridges are amenable to further derivatization, which renders those compounds useful as central units in fragment-based drug discovery or as ligand scaffolds.
