Abstract

N-Fluorination and N-chlorination of methyl 2-trifluoromethylaziridine-2-carboxylate occurs predominantly from the more hindered side owing to the fixed orientation of the lone electron pair of the N atom caused by the formation of an intramolecular H-bond.

Abstract

New N-protected α-CF3 amino esters with two alkene chains (1,7-dienes 3 and 1,6-dienes 5) were reacted with the ring closing metathesis catalyst Ru&z.dbd6;CHPh(Cl)2(PCy3)2 to give the α-CF3 dehydropipecolinate and prolinate derivatives 6 and 7.
