Preparation of beta -N-aziridinopropionates

摘要

beta -N-aziridinopropionates of relatively high boiling alcohols or polyalcohols are prepared by transesterifying a beta -N-aziridinopropionate of a lower alcohol of 1 to 4 carbon atoms with a relatively high boiling alcohol or polyalcohol by a process in which the transesterification is carried out in the presence of, as a transesterification catalyst, a titanium(IV) or tin(IV) compound which is soluble in an organic medium.
