Alkylation of cyclododecanone with ?,?-dibromoalkanes under conditions of phase-transfer catalysis
摘要:
Alkylation of cyclododecanone with alpha,omega-dibromoalkanes Br(CH)(n)Br (n = 3, 4, 5) under conditions of phase-transfer catalysis in the presence of KOH results in the formation of either bicyclic ketones for n = 3 and 5 or a mixture of bicyclic and spirocyclic ketones for n = 4.
