  Stereoselectivity of Addition of Organometallic Reagents to Pentodialdo-1,4-furanoses: Synthesis of L-Axenose and D-Evermicose from a Common Intermediate

  摘要：

  The additions of organometallic reagents to two pentodialdo-1,4-furanosides (methyl 3-O-benzyl-2-deoxy-alpha-D-erythro-pentofuranoside and its beta-anomer) were carried out under a variety of experimental conditions. Methylmagnesium halides, methyllithium, methylcerium and the organotitanium reagent MeTi(OiPr)(3) were reacted with the pentodialdo-1,4-furanosides in an effort to determine if the stereoselectivity of addition to the formyl group is the result of chelation or nonchelation control and to determine the effect of anomeric configuration. The stereochemistry of the products was assigned by NMR methods and correlation with known compounds synthesized previously. The stereoselectivity of addition depends on the configuration at the anomeric center of the dialdose, with the beta-anomer giving mainly the product of a non-chelation-controlled addition and the beta-anomer giving the opposite stereoselectivity. The major product obtained from the beta-anomer was utilized as a key intermediate in the synthesis of two branched-chain carbohydrates, axenose and evermicose, found in antibiotics. Methylcerium additions are the most efficient method for introducing the branching methyl group in a 2-deoxyfuranosid-3-ulose.

  A method for the synthesis of chiral cyclic analogues of platelet-activating factor (PAF) is reported. Treatment of suitably substituted derivatives of 2-deoxy-D-erythro-pentose with phosphorus oxychloride, followed by choline p-toluenesulfonate generates cyclic phospholipids in good yield. Further chemical modification produces other compounds including optically active gamma-butyrolactones such as

  vinyl or propenyl side chain. Extension of the alkene by a Suzuki cross-coupling reaction with 1-bromo-1-(phenylthio)ethene gave thioenol ethers as the cyclization substrates. The treatment of these substrates with BF(3).Et(2)O in tert-butylmethyl ether below 0 degrees C induced cyclization to optically active bicyclic ethers. If the cyclizations are carried out in toluene as the solvent, the isomerization

  In contrast to conventional methods that rely on stoichiometric activation of phosphonylating reagents, we have developed a highly efficient catalytic method for the synthesis of phosphite diesters using a readily available phosphonylation reagent and alcohols with environmentally benign Zn(II) catalysts. Two alcohols could be introduced consecutively on the P center with release of trifluoroethanol
