Dimeric natural products are a collection of molecules with diverse molecular architectures
and significant bio-activities. In this tutorial review, total synthesis of complex dimeric natural …

Present review outlines the advances and perspectives of computational 1H and 13C NMR
applied to the stereochemical studies of inorganic, organic, and bioorganic compounds …

Helical chiral 2-aminopyridinium ions were designed as a significantly more acidic (active)
dual hydrogen-bonding catalyst than commonly used (thio) urea-based systems. The …

Alkaloids are a diverse group of naturally occurring secondary compounds derived from
amino acids or the process of transamination. Some synthetic compounds with similar …

Twenty-one aspidosperma–aspidosperma alkaloids, including the new tabernaesines A–J
(1–9), were obtained from Tabernaemontana pachysiphon. The structures and absolute …

A new family of chiral pyridines has been designed and synthesized for use in asymmetric
organocatalysis. Thus, helical‐chiral pyridines induce high enantioselectivity in a range of …

Tabercorymines A (1) and B (2), two new vobasinyl–ibogan-type bisindole alkaloids with an
unprecedented skeleton, were isolated from Tabernaemontana corymbosa. Their structures …

Four vobasinyl–ibogan type bisindole alkaloids, ervachinines A–D (1–4), along with 12
known terpenoid indole alkaloids, were isolated from the whole plant of Ervatamia …
