  Synthesis of 3-methyl-2-cyclohexenones catalyzed by mercury(II) salts and their microwave assisted BiCl3 catalyzed aldol condensations

  摘要：

  HgSO4 catalyzed hydrative cyclization of 1,6-heptadiynes is present. This reaction proceeded smoothly under the mild condition for differently 4-sustituted 1,6-diynic substrates giving corresponding 3-methyl-2-cyclohexenones with high to excellent yield. The microwave assisted aldol condensation of cyclohexenones under the catalysis of BiCl3 afforded 3-styryl-cyclohexenones with high regio- and stereo-selectivity. (C) 2010 Elsevier B.V.

  New gold-catalyzed cyclization reactions of 1,6-diynes (2,2-dipropargylmalonates) are reported. Symmetrically (Me, Et) and unsymmetrically disubstituted (Me, Et, Ph) 1,6-diynes provided stereoselectively the Z-cyclopentylidene derivatives in 31−60% and 49−83% yield, respectively. High regioselectivity (97:3) was obtained for the cyclization of Me/Ph-substituted 1,6-diynes. A monosubstituted terminal

  报道了新的金催化的1，6-二炔（2，2-二炔丙基丙二酸酯）的环化反应。对称（Me，Et）和不对称双取代（Me，Et，Ph）的1，6-二炔以立体选择性的方式分别提供Z-环亚戊基衍生物，产率为31-60％和49-83％。对于Me / Ph取代的1,6-二炔的环化反应，获得了较高的区域选择性（97：3）。单取代的末端二炔提供了环戊烯衍生物（2-乙酰基-3-烷基环戊-2-烯-1,1-二羧酸酯，43％），而二末端的1,6-二炔（2,2-di（prop-2-丙二酸酯）生成环己烯酮衍生物（3-甲基-5-氧代环己-3-烯-1,1-二羧酸酯，61％）。对于产物的形成，提出了合理的反应机理。
