The exercise says "It is possible to say that gossyplure (this substance) has two cis double bonds. Assign true or false." I have no idea how to solve this. The answer is "false. The first (left to right) double bond is cis, but the last (left to right) is trans." How can I...

Asymmetric reaction of an excess of trans-cyclooctene (1) with chiral bis(dihydrooxazolyl)pyridineruthenium (pybox-ip, 3) complex selectively gives the corresponding ruthenium complex 4R, [RuCl2(pybox-ip){(R)-trans-cyclooctene}], and (S)-trans-cyclooctene 2S. The X-ray crystal structure of...
Asymmetric reaction of an excess of trans-cyclooctene (1) with chiral bis (dihydrooxazolyl) pyridineruthenium (pybox-ip, 3) complex selectively gives the corresponding ruthenium complex 4R, [RuCl_2 (pybox-ip) {(R)-trans-cyclooctene}], and (S)-trans-cyclooctene 2S. The X-ray crystal ...
RutheniumThe chiral {RuCl2(pybox- ip )} fragment can selectively capture the R enantiomer of racemic trans -cyclooctene 1 to give the corresponding complex 2 (see figure) and the free S enantiomer. The crystal structure of 2 is determined by X-ray analysis....
The catalytic reactivity of [MoO2(papy)] in the epoxidation of cis-cyclooctene is described, as well as its ability to effect oxo transfer from DMSO to PPh3.doi:10.1016/j.poly.2019.114312Md. Kamal HossainAnja KhntoppMatti HaukkaMichael G. Richmond...
The existence of the latter two is evidence of the molecule possessing two elements of chirality, a chiral center (C2) and a plane, the diastereoisomers deriving their stability from restricted conformational inversion around the chiral plane. The two diastereomers are capable of thermal ...
