  On the stereochemistry of the Baker's Yeast-mediated reduction of regioisomeric unsaturated aldehydes: Examples of enantioselectivity switch promoted by substrate-engineering

  摘要：

  The Baker's Yeast (BY) reduction of (Z)-2-chloromethyl-3-arylacrylaldehydes was found to afford (R)-2-methyl-3-aryl-propanols showing high enantiomeric excess values. Deuterium incorporation experiments were performed, in order to investigate the mechanism of the bioreduction: the formation of the corresponding substituted 2-benzylacrylaldehydes. as intermediates to be effectively reduced by Baker's Yeast, was suggested. These intermediates were synthesized and submitted to BY reduction to afford the corresponding saturated (R)-alcohols, thus confirming the conclusions drawn from labelling experiments. The enantioselectivity of their bioreduction was found to be opposite with respect to that observed for the corresponding regioisomeric 2-methylcinnamaldehydes. The preparation of the two enantiomers of 2-methyl-3-aryl-propanols by fermentation of two regioisomers represents an interesting example of substrate-controlled enantioselective reaction.

  an effective means to convert methyl 2‐(azidomethyl)‐3‐arylpropenoates and 2‐(azidomethyl)‐3‐arylacrylonitriles to the corresponding iminyl radicals via α‐hydrogen abstraction and subsequent extrusion of dinitrogen. Thus formed iminyl radicals then undergo intramolecular ortho attack on the aryl ring, affording methyl quinoline‐3‐carboxylates and quinoline‐3‐carbonitriles respectively.

  Latent nucleophiles are compounds that are themselves not nucleophilic but can produce a strong nucleophile when activated. Such nucleophiles can expand the scope of Lewis base catalyzed reactions. As a proof of concept, we report that N‐silyl pyrroles, indoles, and carbazoles serve as latent N‐centered nucleophiles in substitution reactions of allylic fluorides catalyzed by Lewis bases. The reactions

  hindered cyclization products (12–23) via the unusual ortho-selective cycloaromatization; while the meta-alkoxy (1i–m, 1r–t) group provided predominantly the ortho-selective 1,3-dien-5-yne cycloaromatization products, meta-Me group (1 n–q), products formed both via ortho-selective cyclization and para-selective cyclization products in comparable ratio. A novel mechanism involving diradical species

  在催化Pd（PPh 3）4和DBU的存在下，Baylis-Hillman醇的丙酸芳基酯的多米诺骨化烯丙基重排，分子内脱羧偶联，炔丙基-丙二烯重排和双自由基1,3-二烯-5-炔环芳构化已经描述了4-苄基萘甲酸的形成。有趣的是，间位取代的丙酸酯（1i – t）通过不寻常的邻位选择性环芳烃化作用提供了空间位阻的环化产物（12 – 23）。而间烷氧基（1i – m，1r –t）组主要提供邻位选择性1,3-二烯基-5yne环芳烃化产品，meta -Me组（1  n – q），是通过邻位选择性环化和对位选择性环化产物以可比的比例形成的产物。已经提出了一种涉及双自由基物种的新机制来解释1，3-二烯-5-炔环芳构化中不寻常的邻位选择性。空间上受阻的邻位选择性环化的优先选择可能归因于具有更稳定的邻位甲氧基环己二烯基团部分（驱动力）的过渡态自由基的形成。
