Abstract

The synthesis of N,N-disubstituted 4-aminobutanal acetals
(XV - XXII) was effected by the hydrogenation of the corresponding
acetylenic analogues. N,N-Disubstituted 4-amino-2-
-butynal acetals (IV-XII) were prepared by the Mannich condensation
of propargylaldehyde acetal, formaldehyde and the corresponding
secondary amine. As an alternative route to N,N-
disubstituted acetylenic aminoacetals, Bodroux-Tschitschibabin
acetal synthesis was also applied in the preparation of 4-dibenzylamino-
2-butynal ac et al (VII).
