The invention relates to the inhibition of vascular endothelial growth factor (VEGF) receptor signaling and hepatocyte growth factor (HGF) receptor signaling. The invention provides compounds and methods for inhibiting VEGF receptor signaling and HGF receptor signaling. The invention also provides compositions and methods for treating cell proliferative diseases and conditions
The invention concerns a process for the preparation of acyl isocyanates which consists of reacting oxalyl chloride with a salt selected from the group consisting of hydrohalides and sulphates of carboxamides and/or carbamates, unsubstituted on nitrogen, then heating the reaction mixture at a temperature between 30.degree. and 150.degree. C. The process is suitable for preparation of acyl isocyanates with excellent yields in easy to control operational conditions.
1-(N-Acyl-carbamoyl)-2-cyanoaziridines of the formula ##STR1## wherein X is oxygen or sulphur, Z is hydrogen or an organic radical, and Y is a carbonyl, sulphonyl, sulphinyl, sulphenyl, phosphoryl or phosphonyl radical, and salts thereof, exhibit immune-stimulating and cancerostatic activities.

Starting fromβ-isocupreidine (β-ICD), a series of difunctional catalysts were synthesized to ascertain their usefulness in the asymmetric Morita–Baylis–Hillman (MBH) reaction. The trichloroacetylcarbamate derivative was found to give the (R)-MBH adducts in excellent optical purities (90–99 % ee) and moderate to good yields (43–83 %), in some cases, better than β-ICD. A number of acrylates were also
