The reaction of spiroepoxycyclohexadienones 1 with TMSCN in the presence of catalytic amounts of Bu4NCN results in the formation of two diastereomeric cyanohydrins. Alternatively, the reaction of 1 with equimolecular amounts of Bu4NCN gave rise to products arising from two other different reaction paths.
Receptortyrosinekinases (RTKs), such as the epidermal growth factor receptor (EGFR) and the platelet-derived growth factor receptor (PDGFR), are critically involved in the transduction of mitogenic signals across the plasma membrane and therefore in the regulation of cell growth and proliferation. Enhanced RTK activity is associated with proliferative diseases such as cancer, psoriasis and atherosclerosis
