摘要：
Relative configuration of the titled racemic compounds la and Ib has been elucidated on the basis of a complete X-ray structure determined for the higher melting diastereoisomer. The compound 1a crystallizes in the orthorhombic space group P2(1)2(1)2, a=15.610(3) Angstrom, b=18.634(4) Angstrom, c=7.5672(7) Angstrom, V=2201.1(6) Angstrom(3), Z=4. Preparative separation of both diasteroisomers is reported.
