Aromatic motifs in the design of Ephedra ligands for application in the asymmetric addition of diethylzinc to aldehydes and diphenylphosphinoylimines

Using N-benzylephedrine as a model, a collection of N-arylmethylephedrine derivatives has been prepared. These derivatives were prepared by treatment of ephedrine with selected aldehydes to create oxazolidines 8a-e. Reduction of the oxazolidines with lith

The Preparation of (1α,3β)-3-Hydroxycholestane-4,6-diene- 1,25-diol Diacetate from a 5,7-Diene Precursor: A New Method for the Synthesis of Heteroannular Dienes

Starting from the 7α-bromide 5a, a regioselective synthesis of (1α,3β)-3-hydroxycholestane-4,6-diene-1,25-diol diacetate (2) is described. The preparative removal of contaminating 5,7-diene 9 was accomplished by the formation of the corresponding Diels-Alder adduct 11. Acetylation of the diacetate 2 followed by acid-catalyzed elimination and rearrangement yielded styrene 13.
