A recently identified phenylpropanoid isolated from Peperomia tetraphylla was synthesized in enantiopure forms using an aldol condensation of enantiopure (R)-N-acetyl 4-phenyl-oxazolidin-2-one as the key step. With ...
The intermolecular Pauson-Khand reaction between 2-ethynylbenzaldehyde and ethylene promoted by dimethyl sulfide can be utilized to synthesize 2-(2-formylphenyl)cyclopentenone efficiently. This compound and its deri...
Some Stemona alkaloids belonging to the tuberostemospironine group possess a spirolactone moiety with anti-configuration (C-9/C-9a). In this paper, we describe two approaches to this structural unity. By using bromi...
Terpenoids comprise the largest family of natural products and include various structurally different genus which play important roles in living organisms. Biosynthetically, diterpenoids are derived from (E,E,E)-ger...
