CA 2566420

The invention provides highly functionalised spiro-fused lactams of formula (I) having a cyclohexane moiety with the desired number of protected or unprotected functional groups or carbonated structures, which are introduced with high stereo and regioselectivity, as well as processes for their obtention. These compounds are useful for the synthesis of a broad range of bioactive molecules, such as condoritols and aminoinositols and their analogues.

Cette invention concerne des lactames spiro-condensés de formule (I) présentant un fragment cyclohexane accompagné du nombre désiré de groupes fonctionnels protégés ou non protégés ou de structures carbonatées, introduits avec une stéréosélectivité et une régiosélectivité élevées, ainsi que leurs méthodes de production. Les composés de l'invention sont utiles pour la synthèse d'une grande variété de molécules, telles que des condoritols et des amino-inositols et leurs analogues.
