ETHYLENIC ACYL CYANIDES IV : INTRAMOLECULAR ENE CYCLISATION OF 5-METHYL-5-HEXENOYL CYANIDES TO 3-METHYL-2-CYCLOHEXENONES
El-Abed, Douniazad,Jellal, Abdelkebir,Santelli, Maurice
, p. 1463 - 1466 (1984)
Condensation of methallyltrimethylsilanes with α,β-ethylenic acyl cyanides leads to 5-methyl-5-hexenoyl cyanides which after thermal cyclisation give 3-methyl-2-cyclohexenones and hydrogen cyanide.
