  对结构简化的底物进行氢化还原环丙基酮的系统研究。通过一分为二的s-顺式构象，可以高度立体选择性地还原反式取代的环丙基酮。

  摘要：

  基于环丙基酮的密度泛函理论（DFT）的从头算计算表明（1）等分的s-顺式和s-反式构象异构体是仅有的两个最小能量构象异构体，而s-顺式构象异构体比s稳定。 -反式和（2）酰基部分中的大体积烷基和环丙烷环上的顺式取代基使平分的s-顺式构象异构体更加稳定。基于这些计算和实验结果，很可能底物的一分为二的s-顺式构象异构体越稳定，氢化物还原的立体选择性就越大。因此，立体化学可以通过氢化物从受阻较少的面上对基底的一分为二的s-顺式构象的攻击来解释。立体化学结果的可预测性基于等分的s-顺式过渡态模型，

• Synthesis of optically active cis- and trans-1,2-disubstituted cyclopropane derivatives by the Simmons-Smith reaction of allyl alcohol derivatives derived from (R)-2,3-O-isopropylideneglyceraldehyde

  The Simmons-Smith reactions of Z- and E-allyl alcohol derivatives 6 derived from (R)-2,3-O-isopropylideneglyceraldehyde (5) were used for the synthesis of optically active cis- and trans-1,2 disubstituted cyclopropane derivatives. Reaction of 6 with diethyl zinc and diiodomethane gave cyclopropane derivatives 7 in 84% to quantitative yields with 35 to approximate to 100% des. Identical facial selectivities toward the double bonds, Ire-asi for Z-6 and 1re-2re for E-6, were observed in the cyclopropanations. The diastereoselectivity was dependent on the protecting group on the terminal allylic oxygen (R of 6, TBDPS > MOM > Bn) and on the stereochemistry of the double bond (Z > E). For TBDPS ethers Z- and E-6c, cis- and trans-7c were obtained as single diastereomers respectively. It was clearly demonstrated that the stereoselectivity of the cyclopropanation is controlled by the directing effect of the allylic oxygen (O-1) of the dioxolane ring which coordinates to the reagent. The terminal allylic oxygen (O-2) lowered the diastereoselectivity This reaction was applied to the synthesis of optically active cyclopropane analogs of gamma-aminobutyric acid (GABA) 18, 22, and ent-22.
• The unusual 1,4-chelation-controlled nucleophilic addition to aldehydes with high stereoselectivity. A systematic study of stereoselectivity in the addition reaction of carbon nucleophiles to cis-substituted cyclopropanecarbaldehydes

  The addition reaction of carbon nucleophiles to cis-substituted cyclopropanecarbaldehydes was systematically investigated. Ab initio calculations of model cyclopropanecarbaldehydes suggested that the bisected s-cis and s-trans conformers are the only two minimum energy conformers, which are stabilized due to the pi-donating stereoelectronic effect of the cyclopropane ring. The experimental results of a series of substrates, that is, cyclopropanecarbaldehydes 1-5 bearing a cis-(tert-butyldiphenyisilyloxy)methyl group, a cis-benzyloxymethyl group, a cis-(p-methoxybenzyloxy)methyl group, cis-N,N-diethylcarbamoyl and trans-phenyl groups, and cis-(tert-butyldiphenylsilyloxy)methyl and trans-phenyl groups, respectively, showed that highly anti-selective Grignard additions could be realized. It turned out that it occurred via an unusual 7-membered 1,4-chelation-controlled pathway. Highly stereoselective Grignard addition via the chelation-controlled pathway occurred even in the reaction of the usually non-chelating silyl ether-type substrate 5. The results have great importance because the 1,4-chelation-controlled stereoselective addition reactions can indeed be realized. Under non-chelation conditions, the syn-products were produced with moderate stereoselectivity, which are likely to be formed via the bisected s-cis conformation-like transition state stabilized by the characteristic orbital interaction. These reactions, especially the chelation-controlled reaction, should be useful because of their t stereoselectivity and stereochemical predictability. (C) 2004 Elsevier Ltd. All rights reserved.
