A New Class of Substrates for the Nucleophilic 5-endo-trig Cyclization, 1-TriCompounds: Synthesis of Indoline and Pyrrolidine Derivatives.
13- 039 fluoromethylvinyl
— The 1-trifluoromethylvinyl system with a nucleophilic part, e.g. (I) and (IV) constitutes a new class of compounds that undergo the normally disfavored 5-endo-trig-cyclization. Depending on the reaction conditions the cyclization is achieved via (i) intramolecular SN2' reaction with loss of a fluoride ion or (ii) intramolecular addition to
the vinylic group. The reaction provides indoline and pyrrolidine derivatives bearing
fluorinated one-carbon units. — (ICHIKAWA*, J.; MORI, T.; IWAI, Y.; Chem. Lett.
