  Hydrogen-bonding patterns of two dihydroxylactone derivatives

  摘要：

  In the hydrogen-bonding networks of 8-hydroxy-5-hydroxymethyl-3,6-dioxatricyclo[6.3.1.0(1.5)]dodecan-2-one and 5,7-bis(hydroxymethyl)-3,6-dioxatricyclo [5.3.1.0(1.5)] undecan-2-one, both C11H16O5, layers and double strands, respectively, lead to the formation of chains connected by hydroxy-to-hydroxy contacts, where the hydroxymethyl group, present in both structures, acts as a donor. The secondary structures differ in the hydrogen bonding of these chains via the second hydroxy group, which is involved in hydroxy-to-carbonyl and hydroxy-to-hydroxy bonds, respectively.

  摘要：

  已经研究了一系列不饱和环己烷羧酸及其酯的氢化立体化学，采用基于CH 2 Cl 2的双（1,4-二苯基膦基）丁铵或吡啶（三环己基膦基）铱基阳离子催化剂。对于3-甲基环己-2-烯甲酸甲酯，在两种情况下都实现了对反式产物的高度选择性还原，而异构体3-亚甲基环己烷甲酸甲酯给出了相当数量的顺式异构体。在相当慢的反应中，在还原4-甲基环己-3-烯丙基羧酸甲酯方面也获得了反式异构体的优势。D 2的还原 揭示了在氢化过程中发生了烯烃双键的相当大的异构化。

  [Graphics]The open-ended hollow tubular structure formed by inclusion of water molecules in the packing of the hydroxyl acid 1 (R-1 = CH2OH, R-2 = ethyl groups) led to the synthesis and structural study of their unsaturated analogues. In this article we report on a general and practical large-scale synthesis of hydroxyl acids that possess alkenyl and alkynyl appendages. Substitution of the ethyl groups in I with unsaturated two-carbon appendages has a different effect on the molecular structure and on the hydrogen-bonding pattern. No variation has been induced by Substitution of only one ethyl group with a vinyl one, although the substitution of both ethyl groups with vinyl or acetylene appendages has the greatest effect on the molecular structure and results in different hydrogen-bonding motifs.
