A new and very convenient one-carbon ring contraction method is reported. Pyrolysis of α-substituted cycloalkanones at 600–650 °C under flow conditions produces the ring contracted compounds under loss of carbon monoxide. Substrates varying in ring size and nature of the α-substituent have been investigated.
报道了一种新的且非常方便的单碳环收缩方法。在流动条件下,α-取代的环烷酮在600–650°C的温度下热解,会在一氧化碳流失的情况下产生收缩的化合物。已经研究了环尺寸和α-取代基性质不同的底物。
