3 Indoles, Oxindoles, and Related Alkaloids 7.3.1 Total Synthesis of Flustramine C 

2 N CP-MAS NMR of Stereoisomeric Oxindole Alkaloids from Cat s Claw (Uncaria tomentosa) 

tomentosa is a woody vine indigenous to the Amazonia rainforest and other tropical areas with hook-like thorns that resemble a cat s claw, hence the name. In 2008, Wawer et al. [51] reported a and CP-MAS NMR study of the oxindole alkaloids of U. tomentosa. The alkaloids for which data were reported included (30), isomitraphylline (31), pteropodine (uncarine C, 32), isopteropodine (uncarine E, 33), and speciophyUine
