Abstract
An intramolecular aminative Umpolung cyclization strategy has been developed by using α,α-diphenylglycine (2) as the amination and Umpolung reagent. Aldehydes (1) bearing an additional carbonyl group underwent condensation with α,α-diphenylglycine to form an imine, decarboxylation to generate a delocalized 2-azaallylanion, and subsequent intramolecular Umpolung cyclization to produce a variety of exocyclic β-amino alcohols (6) in 60-93% yields with up to >20:1 trans/cis selectivity under mild conditions.

Abstract
The enzymatic resolution of (+/-)-trans-10-azido-9-acetoxy-9,10-dihydrophenanthrene by Candida cylindracea lipase-catalyzed hydrolysis was achieved on the gram-scale with excellent yield and enantiomeric excess. The resulting (+)- and (-)-amino alcohols were derivatized to alpha-hydroxy-N-benzenesulphonamides.
