XYZH systems as potential 1,3-dipoles. Part 36. 1,5-Electrocyclisation processes via oxidation of tertiary amines. Pyrrolo-dihydroisoquinolines and -dihydro-β-carbolines.
摘要:
A range of tertiary N-allylamines derived from 1,2,3,4-tetrahydroisoquinoline undergo oxidative cyclisation, induced by Ag2CO3, to pyrrolo-dihydroisoquinolines in moderate to good yield. Analogous oxidative cyclisations are reported for N-allyl-tetrahydro-beta-carbolines and a pyrrolidine. The reactions proceed via formation of a 1,5-dipole followed by an electrocyclisation and subsequent aromatisation.
Described herein are hepatitis B capsid assembly modulators and pharmaceutical compositions comprising said compounds. The subject compounds and compositions are useful for the treatment of hepatitis B.
This communication details the first totalsynthesis of Punicagranine, a new pyrrolizine alkaloid isolated from the peels of the pomengranate, Punica granatum, the basis for traditional Chinese medicine, with anti-inflammatory activity. Two concise, 4–5 step routes were developed to rapidly prepare Punicagranine in 10.7–12.1% overall yields. One route features an intramolecular Heck reaction, while
