Sparteine in PCCP

The dimer sparteine-water has been published in PCCP. Sparteine is a tetracyclic quinilizidine alkaloid used in assymetric synthesis, with two trans and cis conformations. We investigated whether addition of a water molecule flips the molecule by formation of a double hydrogen bond to the cis diamine. However, kinetic reasons explain that the cluster retains the monomer
