  Novel chiral lipoxygenase substrates: design and synthesis. Part 2

  摘要：

  A series of novel lipoxygenase substrates carrying a spacing modifier with a non-ionic hydroxyl terminus have been synthesized in an enantioselective fashion. One of the methylene hydrogens (flanked by the cis,cis-pentadienyl moiety) is replaced by alkyl, aryl and hydroxyl groups. The key steps in the synthesis involved enzymatic transesterification of 1,3-propanediol derivatives and two consecutive cis-selective Wittig olefinations. (C) 2002 Elsevier Science Ltd.

  Chemoenzymatic Approach toward the Pure Enantiomers of 2-Methyl-1,3-propanediol Mono(p-Methoxybenzyl Ether)

  摘要：

  In a route towards the enantiomerically pure 2-methylpropane-1,3-diol mono(p-methoxybenzyl ether), which is an important starting material for natural product synthesis, a kinetic resolution approach by means of lipase-catalyzed hydrolysis as well as acylation has been elaborated. Candida antarctica lipase-catalyzed hydrolysis of the corresponding racemic acetate proceeded with high enantioselectivity (E 35). During the studies, a curious phenomenon was observed, namely, that the enantioselectivity gradually declined accompanying the progress of the hydrolysis. This was due to inhibition of the enzyme-catalyzed reaction caused by the accumulation of the resultant alcohol. The rate of reaction of the more reactive enantiomer became lower. This situation prompted a new process, which would minimize the contamination or the undesired enantiomer, prior to the enzyme-catalyzed hydrolysis. This was successfully achieved with the aid of another Pseudomonas cepacia lipase-catalyzed desymmetrization, taking advantage of the prochiral nature of the starting material, 2-methyl-1,3-propanediol, and the subsequent p-methoxybenzylation under mild conditions.

  A photochemical approach to polysubstituted heterocycles using UV-induced alkene isomerization is described. The method allows for the synthesis of disubstituted furans and pyrroles under mild and neutral conditions and also provides access to a class of trisubstituted furans pertinent to natural-product synthesis. The method has broad functional-group tolerance and many richly decorated heterocycles

• Enantioselective Hydroformylation of 1-Alkenes with Commercial Ph-BPE Ligand

  DOI：10.1021/acs.orglett.5b01421

  日期：2015.7.2

  A rhodium complex, in conjunction with commercially available Ph-BPE ligand, catalyzes the branch-selective asymmetric hydroformylation of 1-alkenes and rapidly generates alpha-chiral aldehydes. A wide range of terminal olefins Including 1-dodecene were examined, and all delivered high enantioselectivity (up to 98:2 er) as well as good branch:linear ratios (up to 15:1).
