Synthesis of aza-1,2-thiophenophanes by double ring enlargement
Heerklotz, J?rg,Linden, Anthony,Hesse, Manfred
, p. 7205 - 7210 (2000)
Two ring enlargement reactions are used to transform the alicyclic 8-membered allyl 2-oxocyclooctane-1-carboxylate (11) to the 13-membered 10-aza-[11]-(2,3)-thiophenophane-1,9-dione (17). The first step yielded the macrocyclic imide allyl N-(3-thienylmeth
Enantioselective synthesis of 3,5-disubstituted thiohydantoins and hydantoins
Chen, Yu,Su, Li,Yang, Xinying,Pan, Wenyan,Fang, Hao

A mild method to convert optically pure amino acid thiourea and urea derivatives to thiohydantoins and hydantoins, respectively, is described. It provides an efficient way to realize enantioselective synthesis of thiohydantoins and hydantoins with good to high isolated yields and enantiomeric purities. We found that the enantiomeric purities were highly dependent on the reaction conditions including bases, solvents, and temperature.
