A synthetic approach to imidazoles annulated to saturated six-membered cycles featuring S, SO, NH, NCbz was developed. It was achieved by combining the Neber rearrangement and the Marckwald reaction. The Neber rearrangement applied to cyclic ketones allowed us to prepare in hundred gram quantities previously unknown α-amino ketones. Unstable tosyl ketoximes were used without purification immediately after their preparation. α-Amino ketones react with potassium thiocyanate and cyanate in almost a quantitative yield affording highly pure imidazol-2-thiones or imidazol-2-ones. Desulfurization of imidazole-2-thiones using Raney nickel led to the formation of previously unknown 2-unsubstituted fused imidazoles in high yields.

This volume contains the proceedings of the ninth workshop on Quantum Physics and Logic (QPL2012) which took place in Brussels from the 10th to the 12th of October 2012. QPL2012 brought together researchers working on mathematical foundations of quantum physics, quantum computing, and spatio-temporal causal structures. The particular focus was on the use of logical tools, ordered algebraic and category-theoretic structures, formal languages, semantical techniques, and other computer science methods for the study of physical behaviour in general.
