Imine synthesis
WitrynaAldehyde Linkers. A type of COFs based on imine linkage, synthesized by condensation of aldehydes and amines, was first reported in 2009, 3) and imine-based COFs have become the most widely reported COFs. One of the advantage of imine based COFs is their higher chemical stability compared to boroxines and boronate esters. WitrynaThe imine Diels–Alder reaction involves the transformation of all-carbon dienes and imine dienophiles into tetrahydropyridines. ... The IDA reaction has been applied to the synthesis of a number of alkaloid natural products. In this example, Danishefsky's diene is used to form a six-membered ring en route to phyllanthine.
