Patent GB-742053-A (GB)
Title: Production of heterocyclic compounds
Inventor: ABBOTT LESLIE STEPHEN
IPC: C07D211/22
Filed: 1952-04-03
Abstract: Substituted N-heterocyclic compounds having a six-membered nitrogen containing ring are prepared by reacting ammonia or a primary monoamine with a substituted aliphatic dialdehyde in which the substituent groups are alkyl and/or alkoxy and/or alkoxyalkyl groups and in which the aldehyde groups are separated by 3 carbon atoms, where the reaction product in the case of ammonia and the said dialdehyde is subjected to reduction with hydrogen or formic acid either before or after completion of the reaction.  The reaction product of the primary amine and the dialdehyde may also be subjected to the reduction referred to above either before or after completion of the reaction to give a substituted N-heterocyclic compound of higher saturation.  The reduction with the reaction product from ammonia or from the primary amine may be effected after the isolation of the initial reaction product.  The hydrogenation is preferably carried out in the presence of a hydrogenation catalyst, e.g.  Raney nickel, platinum or palladium which may be supported on a carrier. The formic acid may be derived from a formic acid yielding material such as a formate or a formamide.  Suitable dialdehyde reactants are alkyl and/or alkoxy and/or alkoxyalkyl substituted glutardialdehydes such as 2-methoxymethyl-2 : 4-dimethylpentane - 1 : 5 - diol, 2 - ethoxymethyl-2 : 4 - dimethylpentane - 1 : 5 - diol and 3-methyl - glutardialdehyde.  The primary monoamine is preferably an aliphatic primary monoamine which may be substituted or unsubstituted, e.g. alkylamines such as methyl-, ethyl- and propyl-amine, and alkylolamines such as ethanol-, propanol- and butanol-amine.  In the examples (1) 6,7,8,9-tetrahydro-7-methoxymethyl - 5,7 - dimethyl - 1 - oxa - 9 - azaindane is obtained by reacting 2-methoxymethyl-2,4 - dimethylpentane - 1,5 - diol and ethanolamine; 1,3,5 - trimethyl - 3 - methoxymethylpiperidine is obtained by reacting methylamine and 2 - methoxymethyl - 2,4 - dimethylpentane-1,5 - diol and hydrogenating the product in the presence of a platinum catalyst; (3) 1,3,5-trimethyl - 3 - methoxymethylpiperidine is obtained as in (2) except that the reduction step is carried out with formic acid; (4) 3,5-dimethyl-3 - methoxymethyl - piperidine is obtained by reacting under pressure 2,4-dimethyl-2-methoxymethyl - pentane - 1,5 - diol, ammonia and hydrogen in the presence of Raney nickel; (5) 4-methylpiperidine is prepared by reacting under pressure 3-methylglutardialdehyde, ammonia and hydrogen in the presence of Raney nickel.
