A new and facile method is proposed for the synthesis of 2-acetonylcyclododecanone and 2-(chloromethyl)-3,5-dioxa-1-hexene under phase transfer catalysis conditions. 2-Methyldecahydrocyclododeca[b]pyrrole and its N-substituted derivatives are easily obtained when 2-acetonylcyclododecanone reacts with ammonia or primary amines. 2-Methyl-N-phenyldecahydrocyclododeca[e]pyrrole was prepared from easily

A simple method is proposed for the alkylation of cyclododecanone by propargyl halides under phase transfer catalysis conditions with the formation of 2-propargylcyclododecanone. The hydration of 2-propargylcyclododecanone upon catalysis by mercury compounds leads to either 14-methyl-13-oxabicyclo[10.3.0]-pentadeca-1(12),14-diene or 2-acetonylcyclododecanone depending on the reaction conditions. Both these compounds are also readily obtained from 2-(2-chloropropen-2-yl)cyclododecanone which readily forms upon the alkylation of cyclododecanone by 1,2-dichloropropene under phase transfer catalysis conditions.
