Synthesis of the C18-Norditerpenoid Alkaloid Neofinaconitine: A Lesson in Convergent Synthesis Planning

Recent Advances in the Chemistry of Saturated Annulated Nitrogen-Containing Polycyclic Compounds

This review is devoted to the analysis of works published over the past 20 years on the chemistry of saturated annulated nitrogen-containing polycyclic compounds, the molecules of which consist of four, five, six, and seven cycles, and contain from one to eight endocyclic nitrogen atoms.

The 1α-hydroxy-A-rings of norditerpenoid alkaloids are twisted-boat conformers

The skeletal conformations of naturally occurring norditerpenoid alkaloids fix their substituent functional groups in space, thereby directing their bioactivities.

Recent advances in the intramolecular Mannich reaction in natural products total synthesis

This review focuses on selected applications of the intramolecular Mannich reaction as a key step in the total synthesis of natural products (2000–2017).

Palladium-catalyzed C–H bond carboxylation of acetanilides: an efficient usage of N,N-dimethyloxamic acid as the carboxylate source

A palladium-catalyzed carboxylation of acetanilide and N,N-dimethyloxamic acid for the synthesis of N-acyl-anthranilic acids is described. N,N-Dimethyloxamic acid can act as an effective carboxylation precursor with K₂S₂O₈ as the oxidant and Pd(OAc)₂ as the catalyst.
