High-Yield Formation of Giant Bis(bicyclic) and Crypt-tris(bicyclic) Molecules under Normal Reaction Conditions

open access: closedThe Journal of Organic Chemistry, 2000
We report the unexpected result of the reaction of 1, 3-bis[(9-anthrylmethoxy)methyl]benzene (1a) or 1,3, 5-tris[(9-anthrylmethoxy)methyl]benzene (1b) with tris(2-maleimidoethyl)amine (2) in homogeneous solution leading to giant bis(bicyclic) and crypt-tris(bicyclic) molecules.

The synthesis of monocyclic and bicyclic molecules and their antioxidant properties

open access: closedJournal of Molecular Structure, 2019
Abstract The synthesis and antioxidant activity of novel cyclitol, lactone and epoxide derivatives starting from appropriate 1.4-cyclohexadiene are reported in this study. All structures of these products were characterized by 1H NMR, 13C NMR, MS and IR spectroscopy.

Synthesis of Bridged Bicyclic Molecules using Halocarbenes. Derivatives of bicyclo[4.2.1]nonane

open access: closedHelvetica Chimica Acta, 1973
AbstractThe addition of dichlorocarbene (generated by the interaction of sodium methoxide and ethyl trichloroacetate) to bicyclo[3.2.1]oct‐2‐ene, its 3‐chloro and exo‐3,4‐dichloro derivatives gives the exo 1 : 1 adducts in yields of 94, 89 and 48%. By suitable chemical reactions of these adducts, convenient syntheses of bicyclo[4.2.1]nona‐2,4‐diene and
