Nonaromatic amidine derivatives as acylation catalysts.

Vladimir B Birman1, Ximin Li, Zhenfu Han.   

Abstract

[reaction: see text] Catalytic activity of nonaromatic bicyclic amidines and bicyclic isothioureas in acylation reactions was found to be remarkably dependent on the sizes of both rings. DBN and especially its thia-analogue (THTP) have been identified as highly active acylation catalysts.
