    • Recrystallization of the diastereomeric mixture of 10 from hexane-EtOAc gave the major diastereomer 10a (>98% de) in 41% yield. The author has deposited atomic coordinates for 10a with the Cambridge Crystallographic Data Centre. The coordinates can be obtained, on request, from the Director, Cambridge Crystallographic Data Centre, 12 Union Road, Cambridge, CB2 IEZ, UK.
