• Asymmetric Michael Addition of a Recyclable Chiral Amine: Inversion of Stereoselectivity Caused by the Difference of Ethereal Solvents

  日期：2008.7.3

  The Michael addition of a chiral amine [(-)- 6] to alpha,beta-unsaturated esters ( 4) was attained and the stereoselectivity was inverted by changing the solvent from diethyl ether to tetrahydrofuran when alpha,beta-unsaturated esters having an aromatic ring at the beta-position were employed. In addition, the chiral auxiliary in the Michael adducts ( 9A) was facilely removed with N-iodosuccinimide

  当α，β-不饱和酯具有芳族化合物时，通过手性胺[（-）-6]的迈克尔加成到α，β-不饱和酯（4）上，并通过将溶剂从乙醚改为四氢呋喃来反转立体选择性。使用在β位的环。此外，用N-碘代琥珀酰亚胺轻松除去了迈克尔加合物（9A）中的手性助剂，得到了β-氨基酯（10A）和2-甲氧基-d-冰片醛（11），可以将其回收为手性胺（ 6）通过还原胺化。

  Secondary homochiral lithium amides derived from α-methylbenzylamine undergo highly diastereoselective conjugate additions to a range of α,β-unsaturated esters. The corresponding β-amino acids are readily liberated by successive N-debenzylation and ester hydrolysis, furnishing (R)-β-amino butyric acid, (R)-β-amino pentanoic acid, (S)-β-leucine, (R)-β-amino octanoic acid, (S)-β-phenylalanine, (S)-β-tyrosine

  衍生自α-甲基苄胺的仲手性锂酰胺会经历高度非对映选择性的共轭加成反应，形成一系列α，β-不饱和酯。通过连续的N-去苄基化和酯水解，可以轻松释放相应的β-氨基酸，从而提供（R）-β-氨基丁酸，（R）-β-氨基戊酸，（S）-β-亮氨酸，（R） -β-氨基辛酸，（S）-β-苯丙氨酸，（S）-β-酪氨酸甲基醚，（S）-β-酪氨酸盐酸盐和（S）-β-（2-甲氧基苯基）-β-氨基丙酸高产和高ee的酸。该程序在天然产物合成中的应用（R证明了）-β-DOPA和（R）-β-赖氨酸。还描述了简化的一锅反应规程的开发，该规程适用于同级手性β-氨基酯的多克规模合成。

  A series of novel dipeptidyl boronic acid proteasome inhibitors composed of beta-amino acids were synthesized, in vitro and in vivo biologically evaluated, and theoretically modeled for the first time. From the screened racemic compounds in enzyme, 4i wits the most active. The IC50 value of its pure enantiomer 4q was 9.6 nM, 36-fold more active than its isomer 4p and as active its the marketed bortezomib in inhibiting human 20S proteasome. This candidate also showed good activities with IC50 values nearly less than 5 mu M against several human solid and hematologic tumor cell lines. Safety evaluation in vivo with zebrafish and Sprague-Dawley (SD) rats showed that the candidate 4q was less toxic than bortezomib. Pharmacokinetic profiles suggested candidate 4q showed a more plasma exposure and longer half-life than bortezomib. Docking results indicated that 4q nearly interacted with 20S proteasome in it similar way as bortezomib.
• Enantiopure 3-Amino-Substituted 1-Indanones, 1-Tetralones, and 1-Benzosuberones via Friedel–Crafts Cyclisation of ω-Aryl-β-benz­amido Acids
  作者：Stephen Davies、Euan Goddard、Paul Roberts、Angela Russell、James Thomson

  DOI：10.1055/s-0034-1380675

  日期：——

  Conjugate addition of enantiopure lithium (R)-N-benzyl-N-(-methylbenzyl)amide to a range of -aryl-,-unsaturated esters gives the corresponding -aryl--amino esters as single diastereoisomers in high yields. Friedel-Crafts cyclisation of the pendant carbonyl group onto the -aryl ring then gives a range of 3-amino-substituted 1-indanones, 1-tetralones, and 1-benzosuberones, representing an efficient and short protocol for the preparation of these benzo-fused carbocycles in enantiopure form.
