Starting material for asymmetric epoxidation.1,2 | [Structure and conformation]
1,4-pentadien-3-ol (CH2=CH-CH(OH)-CH=CH2) is a representative allyl alcohol containing two C=C bonds and one hydroxyl group. It has a complicated conformational landscape arising from the rotations of three σ-bonds, i.e. three dihedral angles of ?(C7=C6-C1-O3), ?(C5=C4-C1-O3), and ?(H8-O3-C1-H2). Experiments and ab initio calculations revealed that the 1,4-pentadien-3-ol monomer prefers a configuration with one vinyl being syn to the hydroxyl oxygen and the hydroxyl hydrogen toward the skew-arranged vinyl, which therefore makes possible simultaneous C-H···O and O-H···π interactions[1].
