Modular asymmetric synthesis of functionalized azaspirocycles based on the sulfoximine auxiliary
Azaspirocycles are found as structural motif in a number of highly interesting natural products. In particular the marine alkaloid halichlorine has been target of many synthetic approaches because of its interesting biological activities and intricate structure. Even so there is still an interest …

Studies on Syntheses of 1-Azaspirocycles, 2,6-Disubstituted 3-Piperidinols and cls-Decahydroquinolines
Pyrrolidines and piperidines bearing a nitrogen-substituted quaternary stereocenter are commonly encountered structural motifs in many naturally occurring alkaloids, and therefore development of methods for their synthesis are important. The Rh(II)-catalyzed intramolecular tertiary C-H insertion …
