英文摘要 | Highly enantioselective rhodium-catalyzed nitroallylations of arylboronic acids and arylzinc chlorides with cyclic nitroallyl acetates are described. catalyst screening indicated that the rhodium complex of [rh(oh)(cod)](2) and optically pure binap is the optimal catalyst for the nitroallylation of arylboronic acids with 2-nitrocyclohex-2-enyl esters, providing good yields and high enantioselectivities of up to 99% ee. the rhodium complex prepared from rh(acac)(c2h4)(2) and (r)-binap efficiently catalyzed the nitroallylation of arylzinc chlorides with 2-nitrocyclohex-2-enyl acetate at 0 degrees c in high yields of up to 93% and with high enantioselectivities of up to 96% ee. a number of synthetically useful intermediates with high optical purity were prepared with this reaction as starting point: concise total syntheses of optically pure (+)-beta-lycorane in 53% overall yield and of (+)-gamma-lycorane in 52% overall yield were achieved by commencing with the asymmetric nitroallylation of 3,4-methylenedioxyphenylzinc chloride with 2-nitrocyclohex-2-enyl acetate.
