Pyridine derivatives

Inverse Electron-Demand Aza-[4 + 2] Cycloaddition Reactions of Allenamides.
Allenamides can undergo Diels—Alder reaction with some 1-azadienes to afford
50- 106 —
pyridine derivatives. In most cases the reaction proceeds with low stereoselectivity.
However, the products can smoothly be converted into other interesting chiral pyridine
derivatives such as aza-glycoside related compounds. A drawback of this method is difficult and limited accessibility of appropriate 1-azadiene substrates. — (BERRY, C.
