A concise, stereoselective synthesis of 1-deoxygulonojirimycin was achieved and the absolute configuration of the natural product was revised. Key features involve diastereoselective oxazoline formation catalyzed by palladium(0), RCM and dihydroxylat

Our synthesis of (+)-spectaline revealed that the methodology involving diastereoselective palladium(0)-catalyzed oxazoline formation and intramolecular reductive amination by catalytic hydrogenation of an oxazoline is an effective method for the asy

Pd(0)-catalyzed arylation of the aryl-substituted α-allenic alcohols with hypervalent iodonium salts afforded substituted trans-epoxides. Alternatively, arylation of the alkyl-substituted α-allenic alcohols in the presence of K 2 CO 3 afforded syn-
