First asymmetric synthesis of the natural enantiomer of the indolizidino[8,7-b]indole alkaloid harmicine
We report a novel, facile and asymmetric approach for the synthesis of the indole alkaloid harmicine via a highly diastereoselective N-acyliminium cyclization reaction as a key synthetic step, and verify the relative stereochemistry of the key synthetic intermediate in this approach through X-ray crystallography
A formal asymmetric synthesis of both enantiomers of the Erythrina Alkaloid 3-Demethoxyerythratidinone
A formal asymmetric synthesis of both enantiomers of the Erythrina alkaloid 3-
demethoxyerythratidinone is reported through the application of a highly functionalised lactam template as
an N-acyliminium precursor
An asymmetric synthesis of both enantiomers of the indole alkaloid deplancheine
We report a novel, facile and asymmetric approach to both enantiomers of the indole alkaloid deplancheine from a readily available, non-racemic chiral template. The natural product, and its antipode, are isolated with >95% e.e
A new asymmetric synthesis of the anti-tumour alkaloid (R)-(+)-crispine A
We report a novel, facile and asymmetric approach for the synthesis of the anti-tumour alkaloid (+)-crispine A via a highly diastereoselective N-acyliminium cyclization reaction as a key synthetic step
