How to use in-sentence of “disrotatory”:
+ The orbital mechanics of the reaction needs a disrotatory mode.
+ Linear approaches will have conrotatory motion while non-linear approaches will have disrotatory motion.
+ If aromatic, linear approaches use disrotatory motion while non-linear approaches use conrotatory motion.
+ Only a disrotatory mode, in which symmetry about a reflection plane is maintained throughout the reaction, would result in maximum orbital overlap in the transition state.
+ In a typical electrocyclic ring closing, selection for either conrotatory or disrotatory reactions modes still produces two enantiomers.
