  • Preparation of Optically Enriched Secondary Alkyllithium and Alkylcopper Reagents—Synthesis of (−)‐Lardolure and Siphonarienal

    converted into secondary alkyllithium and secondary alkylcopper compounds with very high retention of configuration. Quenching with various electrophiles, including chiral epoxides, provided a range of chiral molecules with high enantiomeric purity (>90 % ee). This method has been applied in an iterative fashion in the total synthesis of (−)‐lardolure in 13 steps and 5.4 % overall yield (>99 % ee, dr>99:1)

  • Chemoenzymatic Approach toward the Pure Enantiomers of 2-Methyl-1,3-propanediol Mono(p-Methoxybenzyl Ether)
    作者:Tomohiro Akeboshi、Yoshikazu Ohtsuka、Takashi Ishihara、Takeshi Sugai
    DOI:10.1002/1615-4169(200108)343:6/7<624::aid-adsc624>3.3.co;2-h
    日期:2001.8
    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.
