An enantioselective route to four tricyclic amino acids and N-tosylamides, composed of a central norbornane framework with a 2-endo,3-endo-annelated pyrrolidine ring and a 5-endo-C1 or -C2 side chain, has been developed. A key intermediate was the chiral,

(Thio)urea-mediated synthesis of functionalized six-membered rings with multiple chiral centers
Organocatalysis, now running its second decade of life, is being considered one of the main tools a synthetic chemist has to perform asymmetric catalysis. In this review the synthesis of six-membered rings, that contain multiple chiral centers, either by

Extending Highthroughput Technologies: The Automation of Mechanism Discovery Investigations into the mode and action of the thio-Michael Reaction [PDF]
This project concerns the investigation of the thio-Michael reaction (see scheme). The approach has employed a process development methodology to chemical discovery rather than more traditional research methods.
