    An efficient catalytic double asymmetric induction during the tandem transetherification–intramolecular hetero Diels–Alder reaction has been developed. The enantioselective tandem reaction of methyl (E)-4-methoxy-2-oxo-3-butenoate with rac-6-methyl-5-hepten-2-ol has been achieved to provide methyl (2R,4aS,8aR)-3,4,4a,8a-tetrahydro-2,5,5-trimethyl-2H,5H-pyrano[4,3-b]-pyran-7-carboxylate in good yield

    β-unsaturated α-oxo esters 1a−d and cyclic and acyclic ketone enol ethers 2a−l afforded heteroadducts 3−5 in high yields when either [Eu(fod)3] or SnCl4 were used as the catalyst. With methyl (E)-benzylidenepyruvate (1a), the two catalytic modes displayed divergent stereoselectivities. In the case of the heterocycloaddition of silyl enol ether 2h, X-ray investigations established the relative configurations
    (E)-γ-取代的β-不饱和α-氧代酯1a-d与环状和非环状酮烯醇醚2a-l之间的[4+2]杂环加成反应以高产率提供杂加合物3-5,当[Eu(fod )3] 或 SnCl4 用作催化剂。对于 (E)-亚苄基丙酮酸甲酯 (1a),两种催化模式显示出不同的立体选择性。在甲硅烷基烯醇醚 2h 的杂环加成的情况下,X 射线研究确定了双环加合物 3h 和 5h 的相对构型,分别作为 [Eu(fod)3] 和 SnCl4 的主要异构体获得。这些分配提供了有关这些酸催化反应的协调与非协调机制的宝贵信息。与(E)-叔丁氧基亚甲基丙酮酸甲酯(1d),事实证明,反应范围仅限于作为亲二烯体的烷基烯醇醚。在这种情况下,立体化学过程遵循不同的途径,例如加合物 4q 的 X 射线结构,当 SnCl4 是催化剂时,从 1d 和 1-甲氧基环己烯 (2f) 以总立体选择性获得。

    cycloadditions of 4-substituted methyl 2-oxo-3-butenoates and -3-pentenoates with alkenes took place with high regio- and stereoselectivities to afford substituted 6-methoxycarbonyl-3,4-dihydro-2H-pyrans in good to moderate yields. None of the ene products were produced. Similar reactions of methyl 3-phenyl-2-oxo-3-butenoate with alkenes afforded both the corresponding 3,4-dihydro-2H-pyrans and a dimeric cycloadduct

    β-Alkoxy-substituted α,β-unsaturated carbonyl compounds activated with an additional electron-withdrawing substituent undergo a facile tandem transetherification/intramolecular hetero Diels–Alder reactions when reacted with δ,ε-unsaturated alcohols under thermal conditions. These reactions are stereoselective producing the corresponding functionalized hydropyranopyran derivatives in good yields.
