  Synthesis of 3-methyl- and 3,4-dimethylfurans using alkoxide, thiolate, and phenoxide-mediated cyclization of 4-oxahepta-1,6-diynes bearing sulfur and selenium functional groups

  摘要：

  We have reported sodium alkoxide- or aryloxide-mediated cyclization of 4-oxahepta-1,6-diynes bearing the phenylsulfanyl group 1a-d. The reactions with diverse sodium alkoxides and aryloxide produced 4-alkoxymethyl- and 4-aryloxymethylfurans 2aa-2db in good to high yields. Although reactions with sodium benzenethiolate yielded 3,4-bis(phenylsulfanylmethyl)furans 5a-g, they readily desulfanylated in the presence of tributyltin hydride/AIBN to give the 3-methyl- and 3,4-dimethylfuran derivatives 6a-g. This method's utility was demonstrated by the synthesis of tetrahydronaphthalenyl furan derivatives bearing alkoxy- and aryloxymethyl substituents. (C) 2011 Elsevier Ltd. All rights reserved.

  Direct scandium- and lanthanum-catalyzed etherifications of propargyl alcohols 1 and 6 in MeNO2–H2O provided propargyl ethers 3, 4 and 7 in high yields. In addition, reactions of 1 and 6 with thiols exclusively yielded the corresponding propargyl sulfides.

  Propargylations of 1,3-diketones using 3-sulfanyl and 3-selanylpropargyl alcohols 1 in MeNO2–H2O gave alkynyl ketones 2a—m, 2o—v and 6,7-dihydro-5H-cyclohexa[b]pyran-5-ones 3k—n. With some bases, the useful propargylated 1,3-diketones underwent intramolecular cyclization to give 6,7-dihydro-5H-benzofuran-4-ones 4a—i or 4,5,6,7-tetrahydrobenzofurans 5p, 6p—v.

  使用3-硫基和3-硒基丙炔醇1在MeNO2-H2O中对1,3-二酮进行丙炔化反应，得到了烷炔酮2a—m、2o—v以及6,7-二氢-5H-环己[b]吡喃-5-酮3k—n。与一些碱反应时，有效的丙炔化1,3-二酮发生分子内环化，生成6,7-二氢-5H-苯并呋喃-4-酮4a—i或4,5,6,7-四氢苯并呋喃5p、6p—v。

  Pyrazoles direct: Propargyl alcohols undergo hydrazination when treated with p‐tosyl hydrazide in the presence of catalytic amounts of either Sc(OTf)3 or La(OTf)3 (see scheme; Tf=trifluoromethanesulfonyl). Propargyl hydrazides are converted into either N‐tosyl or N‐H pyrazoles when treated with an acid or a base, respectively. The one‐step acid‐catalyzed hydrazination/cyclization of propargyl alcohols

  直接吡唑：在催化量的Sc（OTf）3或La（OTf）3存在下，用对甲苯磺酰基酰肼处理时，炔丙醇会发生酰化作用（见方案； Tf =三氟甲磺酰基）。分别用酸或碱处理时，炔丙基酰肼可分别转化为N-甲苯磺酰基或N- H吡唑。炔丙醇的一步酸催化肼化/环化反应可直接获得高产率的吡唑。
