  Stereoselective acetalization of 1,3-alkanediols by l-menthone: application to the resolution of racemic 1,3-alkanediols and to the determination of the absolute configuration of enantiomeric 1,3-alkanediols

  摘要：

  A general and reliable method for the resolution of racemic 1,3-alkanediols, which involves their conversion into diastereomeric spiroacetals derived from l-menthone, is described. Thus, the reaction of the bis-O-trimethylsilyl derivatives of racemic 1,3-alkanediols with l-menthone in the presence of a catalytic amount of trimethylsilyl trifluoromethanesulfonate affords the diastereomeric spiroacetals 3 and 4. The two can be readily separated by silica gel column chromatography. Hydrolysis of each diastereomer under acidic conditions liberates the corresponding enantiomerically pure diol. An empirically derived correlation of configuration and H-1 NMR chemical shifts for spiroacetals 3 and 4 has been developed which is rationalized based on long-range effects due to the magnetic anisotropy inherent to the menthane ring in a rigid spiroacetal conformation. The method described here should be widely applicable to the determination of the absolute configuration of various 1,3-alkanediols.

• Dimethylzinc-Mediated, Oxidatively Promoted Reformatsky Reaction of Ethyl Iodoacetate with Aldehydes and Ketones

  日期：2008.5.5

  A practical and general Reformatsky reaction, promoted by oxidants and mediated by dimethylzinc, is described. The reaction is fast and runs at 0 °C with aldehydes and ketones, under mild reaction conditions. Preliminary results obtained for the enantioselective version show that inexpensive chiral amino alcohols could be used in the challenging formation of enantioenriched quaternary stereogenic centers

  Efficient and practical in situ zinc activation was accomplished by treatment with catalytic amount of an organic acid. The protocol was applied successfully to the Blaise reaction of various nitriles. Noteworthy is the excellent Blaise transformation of (S)-4-chloro-3-trimethylsilyloxybutyronitrile (2b) into tert-butyl (S)-6-chloro-5-hydroxy-3-oxohexanoate (1), a key intermediate for the preparation of HMG-CoA reductase inhibitors (statins).

• The Structure of Viscosin, A Peptide Antibiotic. I. Syntheses of D-and L-3-Hydroxyacyl-L-leucine Hydrazides Related to Viscosin

  Sixteen D- and L-3-hydroxyacyl-L-leucine hydrazides related to viscosin have been synthesized. Condensation of DL-3-hydroxy fatty acids with L-leucine methyl ester by the azide method or the active ester method gave DL-3-hydroxyacyl-L-leucine methyl esters, which were then converted to their hydrazides. Each of the racemic hydrazides could readily be resolved into the respective optically active diastereoisomers by means of fractional crystallization using alcohols. All of the D- and L-3-hydroxyacyl-L-leucine hydrazides prepared showed antimicrobial activity against four kinds of microorganisms only comparable to or less than that of the saturated straight chain fatty acids of corresponding carbon numbers.
