Synthesis and photocyclization of macrocyclic stilbene derivatives
Dyker, Gerald,K?rning, Jutta,Stirner, Wolfgang
, p. 149 - 154 (2007/10/03)
The stereoselectivity of the formation of macrocyclic stilbenes as well as the regioselectivity of their photocyclization are strongly influenced by the length of the connecting alkanediyl chain. The stereoisomers of the macrocyclic stilbenes and the corr
