  • Method of preparing cis-8b-methyldecahydro-2a,4a,6a,8a-tetraazacyclopenta[fg] acenaphthylene, cis-decahydro-2a,4a,6a,8a-tetraazacyclopenta[fg] acenaphthylene, cyclene and functionalised cyclenes
    Publication number: 20060217548
    Abstract: A method of preparing cyclene having formula (I) from triethylenetetraamine having formula (VIII) or ethylenediamine having formula (VIII?) includes a series of steps. The first series of steps (I) includes a step A (one-pot preparation of the compound having formula (IIa) from the compound having formula (VIII)), followed by a step B (transforming the compound having formula (IIa) into cyclene having formula (I)). The second series of steps (II) includes a step C (preparing the compound having formula (IIb) from the compound having formula (VIII)), followed by a step D (transforming the compound having formula (IIb) into cylcene having formula (I)). The third series of steps (III) includes a step E involving the one-pot preparation of the compound having formula (IIa) from the compound having formula (VIII), followed by a step B involving the transformation of the compound having formula (IIa) into cyclene having formula (I).
