    摘要:
    报道了Manumycin A作为其(+)-对映异构体的第一个全合成。该合成路线具有不对称环氧化(基于Wynberg手性相转移方法)的特点,用于制备关键的环氧喹啉核,并进一步证明了Stille反应在构建Manumycin下部侧链方面的效用。Manumycin A的这种合成纠正了原来的立体化学分配,并确认了顺式-羟基环氧化物的排列。还描述了通过Manumycins AC的氧化降解获得的醌的第一合成。

  • Highly Enantioselective Hydroformylation of Olefins Catalyzed by Rhodium(I) Complexes of New Chiral Phosphine−Phosphite Ligands

    1‘-binaphthalen-2‘-yl (S)-1,1‘-binaphthalene-2,2‘-diyl phosphite [(R,S)-BINAPHOS, (R,S)-2a], was synthesized. Its Rh(I) complex was prepared, and its structure has been characterized by 1H and 31P NMR spectroscopy. Using Rh(I) complexes of (R,S)-2a and its enantiomer, highly enantioselective hydroformylation of styrene has been performed (94% ee, iso/normal = 88/12). The catalyst system was also effective

    作者:Gary M. Noonan、José A. Fuentes、Christopher J. Cobley、Matthew L. Clarke
    DOI:10.1002/anie.201108203
    日期:2012.3.5
    Surprising selectivity: The first enantioselective hydroformylations of simple alkenes of type RCH2CHCH2 to preferentially deliver the branched aldehyde product have been discovered using a new chiral ligand, named bobphos (see scheme). Established ligands are unselective in this reaction or show a slight preference towards the linear aldehyde.
    令人惊讶的选择性:使用名为bobphos的新手性配体发现了RCH 2 CH = CH 2类型的简单烯烃优先递送支链醛产物的首次对映选择性加氢甲酰基化。建立的配体在该反应中是非选择性的,或对线性醛显示出轻微的偏爱。

    The present invention relates to a process for producing an optically active 2-substituted propanal derivative, and more particularly, a process for producing an optically active 2-substituted propanal derivative which comprises stereoselectively reducing a carbon-carbon double bond of a 2-substituted acrolein derivative by using an enzyme source capable of stereoselectively reducing said carbon-carbon double bond. According to the present invention, it becomes possible to produce an optically active 2-substituted propanal derivative, in particular an optically active 2-alkylpropanal derivative, which is useful as an intermediate of pharmaceutical products, sweetening agents, etc., in a convenient manner from inexpensive and easily available materials.

  • Asymmetric hydroformylation catalyzed by an Rh(I)-(R, S)-BINAPHOS complex: substituent effects in olefins on the regioselectivity
    作者:Kyoko Nozaki、Tetsuo Nanno、Hidemasa Takaya
    DOI:10.1016/s0022-328x(96)06620-x
    日期:1997.1
    Olefins bearing the larger substituents at the allylic position were hydroformylated in the higher iso/normal selectivity when Rh(I)-(R,S)-BINAPHOS was used as a catalyst. Deuterioformylation of 4,4,4-triphenyl-1-butene suggests that the higher iso/normal ratio may be attributed to the accelerated CO insertion to the iso-alkylrhodium 7i.
