experimental part, p. 1243 - 1252 (2009/11/30)
Two homoproline derivatives containing either the 5-thioxo-1,2,4-oxadiazole or the 2-oxo-1,2,3,5-oxathiodiazole bioisosteric groups, in replacement of the carboxyl group, were synthesized and their catalytic activities in Michael reactions were evaluated.

A new homo-proline tetrazole derivative 7 has been prepared and shown to have improved properties for achieving asymmetric Michael addition of carbonyl compounds to nitro-olefins.
Synthesis of tetradentate bisamino-bisthiol complexes of oxorhenium(V) as structural mimics of steroids
Sugano, Yuichi,Katzenellenbogen, John A.
, p. 361 - 366 (2007/10/03)
Two tetradentate chelate systems have been synthesized in order to prepare metal complexes with oxorhenium(V) whose structures will mimic that of steroids. The chelate system with amide/amine/thioether/thiol donor sites failed to give a stable complex, bu
THE SYNTHESIS OF (-)-ISORETRONECANOL, (-)-TRACHELANTHAMIDINE, AND (-)-SUPINIDINE FROM (S)-PROLINE
Rueeger, Heinrich,Benn, Michael
, p. 1677 - 1680 (2007/10/02)
Dieckmann cyclisation of (S)-N,2-di(carboethoxymethyl)pyrrolidine, made from (S)-proline, gave (8S)-1-carboethoxypyrrolizidin-2-one, which was then converted into (-)-isoretronecanol, (-)-trachelanthamidine, and (-)-supinidine.
