A new class of chiral phosphines belonging to the P-aryl-2-phosphabicyclo[3.3.0]octane family (PBO) has been prepared by enantioselective synthesis starting from lactate esters and 2,2-dimethylcyclopentanone enolate 5. A selective enolate alkylation method has been developed for preparation of 9 and 10...

Up to the present, numerous vitamin D derivatives have been synthesized, but most of them have straight side chains, and there are few publications described about in vitro and in vivo evaluations on bone by vitamin D derivatives. In our...

2,6,6-Trimethyl-2-azaspiro[4.4]nonane-1,3-dione (9), a spirosuccinimide moiety of asperparaline A (1), was synthesized by starting from 2,2-dimethylcyclopentanone (4) via trinitrile 6 in five steps in a moderate yield. This conversion establishes a model study for synthesis of the spirosuccinimide moiety of asperparaline...
