(±)-Stemoamide (1) was prepared in seven steps beginning with γ-chlorobutryl chloride (20)
and succinimide (15), which were efficiently converted to the key alkyne oxazole 17 on a …

The proposed structures of parvistemoamide have been achieved by macrolactamization,
but none of the characterization data of synthetic samples matched with those of the natural …

Total syntheses of (−)-stemospironine and three new diastereoisomeric analogs have been
completed through a flexible strategy devised for Stemona alkaloids. The azabicycle 7 is the …

Stemona alkaloids form a unique class, which can be attributed to hemiterpenoid pyrrolidine-

Herein we report the results of a furan-based approach toward the synthesis of the Stemona
alkaloid, stemocurtisine 1 via the linearly fused tricyclic intermediate 3, representing the key …

Main observation and conclusion A phytochemical investigation on the seeds of Sophora
alopecuroides led to obtaining fourteen structurally diverse matrine‐based alkaloids (1 …

Stemoamide (1) is a member of the stemona class of alkaloids that was isolated in 1992
from the roots of Stemona tuberosa (Figure 1). 1a Alkaloids of this genus typically …

In recent years, researches on the total syntheses of Stemona alkaloids with different 5/7
