(EN) The instant invention is a selective formation of the Z-oxime and O-alkylation of 1-azabicyclo-(2.2.1)heptan-3-one and 1-azabicyclo(2.2.2)heptan-3-one oximes (I) to produce compounds with muscarinic activity. The process is capable of scale-up for industrial purposes as it provides better yields and ease of preparation. Intermediates are also described.(FR) L'invention se rapporte à la formation sélective de l'oxime Z et à l'alkylation O des oximes 1-azabicyclo-(2.2.1)heptan-3-one et 1-azabicyclo(2.2.2)heptan-3-one afin de produire des composés à activité muscarinique. Le procédé peut être étendu à des fins industrielles du fait qu'il assure de meilleurs rendements et une facilité de préparation. Des intermédiaires sont également décrits.

The instant invention is a selective formation of the Z-oxime and O-alkylation of 1-azabicyclo 2.2.1!heptan-3-one and 1-azabicyclo 2.2.2!heptan-3-one oximes to produce compounds with muscarinic activity. The process is capable of scale-up for industrial purposes as it provides better yields and ease of preparation. Intermediates are also described.
