【Abstract】 Under the action of a low valent titanium reagent, substituted imidazolidines were synthesized in moderate yields via cross coupling between imines and triethyl orthoformate, and the yields of product 3 with different substituted groups as well as the corresponding isomer distributions were also discussed. Related NMR spectra were used to define the configuration of the products.更多还原
