  • Convenient Catalytic Synthesis and Assignment of the Absolute Configuration of Enantiomerically Pure Dihydronaphthalenes and Their Corresponding Epoxides

    DOI:10.1002/(sici)1521-3765(19981002)4:10<1944::aid-chem1944>3.0.co;2-l
    日期:1998.10.2
    In this paper we report on the synthesis and kinetic resolution of 1,2-dihydronaphthalenes by Jacobsen epoxidation, which proceeds smoothly with good selectivity (k(rel)=6.3-9.1). The yields were conveniently adjusted by variation of the number of equivalents of MCPBA (m-chloroperoxybenzoic acid) as the terminal oxidant, to afford enantiomerically pure starting materials or epoxides after one recrystallization. Complete separation of the starting material and the epoxides was effected by HPLC with a chiral stationary phase. Interestingly, the Jacobsen epoxidations afford two diastereomers, whereas the reaction with MCPBA alone proceeds with high diastereoselectivity. This can be attributed to unfavorable steric interactions and a matched-mismatched pair in the transition states. The relative configuration of both diastereomers was elucidated by detailed NMR spectroscopy. Furthermore, the absolute configuration of all the products was established unequivocally by comparison of experimental and calculated circular dichroism (CD) spectra. Since the epoxides can be transformed into the etoposide skeleton in only three steps, the kinetic resolution described herein offers simple access to optically active derivatives of these important anticancer drugs.
