ChemInform Abstract: SYNTHESIS OF 1,3‐DIOXOLANE DERIVATIVES FROM 1‐FORMYLCYCLOHEXENES AND STUDY OF THEIR PROPERTIES

Abstract

Durch Kondensation des Diols (I) mit den Cyclohexenylaldehyden (II) werden die Cyclohexenyldioxolane (III) erhalten.

On Dioxolanation Reaction of Cyclohex-3-Ene-1- Carbaldehydes With 1,2-Diols and Properties of Prepared Products

“…They are insoluble in water, well dissolved in organic solvents (acetone, ether, ethanol, etc). The physicalchemical constants, as well as data of elemental analysis and spectral indices of the synthesized compounds (IΧ-ΧΧΙI) and products of their conversion (ΧΧΙIΙ-LIΙI) were offered in the work [22] and following publications [1,3,4,17,[22][23][24][25]. Owing to the fact that the creation of polymer composition materials with high operational properties based on industrial epoxide resins is topical, especially as it becomes increasingly important with the growth of technological progress, as exemplified by some representatives among the synthesized compounds (XLV-XLVII).…”

“…It should be noted that the implementation of cyclization with conversion of "RH" in enol ether is impeded due to unlikelihood of proton's tearing away from sp 3 of the hybridized carbon atom of carbocycle in these conditions. Consequently, the implementation of cyclization through enol ether would lead to extremely low yields of the corresponding basic product which is contrary to the experimental data [22][23][24][25]. The incapacity of cyclization by means of formation of intermediate with endo-carbonoxygen double bond was convincingly proved in the work [21], based on Baldwin rule for ring closure [26].…”
