Ghirga, Francesca published the artcileUndecenyl resorc[4]arene in the chair conformation as preorganized synthon for olefin metathesis, Category: catalysis-chemistry, the publication is RSC Advances (2013), 3(38), 17567-17576, database is CAplus.
Tetramerization of (E)-2,4-dimethoxycinnamic acid ¦Ø-undecenyl ester with ethereal BF3 gave three stereoisomers 1a, 1b, and 1c, which were assigned as the chair, cone, and 1,2-alternate conformations, resp. The chair conformation of 1a was confirmed by X-ray diffraction anal., which also showed a peculiar self-assembly behavior in the crystal lattice, forming intercalated hydrophilic and hydrophobic layers (6-7 ? thickness) as a consequence of strong CH-¦Ð interactions. Undecenyl resorc[4]arene 1a, which featured the simplest pattern of substituents, was submitted to olefin metathesis using the second-generation Grubbs complex as the catalyst. Depending on the reaction conditions, different products were isolated: a bicyclic alkene 2a (46%), a linear dimer 3a (5%), and a cross-linked homopolymer P1a (44%).
