The rearrangement of cyclopropyl carbenes
… was concerned with experimental studies on the rearrangement of cyclopropyl carbenes, generated by the decomposition of the p-toluene sulphonyl hydrazones of<br/>cyclopropyl aldehydes and ketones at 135 - 140° in an alkaline aprotic medium.<br/><br/>Cyclopropane carboxaldehyde p-toluene …

A systematic study of Wallach rearrangement
… a systematic steady of acid-catalysed Wallach rearrangements of a large number of symmetrical di- and tetrasubstituted azoxybenzenes. A second aim was the synthesis of new polysubstituted hydroxyazobenzenes."

Genome Rearrangement, Randic Index and Routing Number
… discrete mathematics are studied:</p> <p>Genome rearrangements are to represent evolusion of genomes as signed or unsigned permutations of genes and compute their distances based on the minimum number of certain operations (evolutionary events) needed to transform one permutation into another. …

Synthetic applications of the aza-Achmatowicz rearrangement
… compounds has been achieved. The oxidative rearrangement of N-acyl 2-furylamines, termed the Aza-Achmatowicz rearrangement, generates a product with a high density of differentiable functionalities. This characteristic of the product makes it an excellent building block for the synthesis of …

Alpha-Oxygenation by Acylation-Rearrangement of Nitrones
The acylation-rearrangement of N-alkylnitrones with acid chlorides and triethylamine affords a new method for the (alpha)-oxygenation of aldehydes and cyclic ketones via (alpha)-acyloxy imines. The reaction apparently proceeds by initial acylation of the nitrone oxygen, proton removal, and …

Genome reconstruction and combinatoric analyses of rearrangement evolution
… with a high number of large-scale, structural rearrangements. In a highly selective environment, some `driver' mutations conferring clonal growth advantage will be positively selected, accounting for further cancer development. Clarifying their nature, as well as their contribution to the …

Modified Purines. Rearrangement Through 5-Substituted Purine Intermediates
A novel rearrangement has been utilized for the synthesis of imidazo{1,5-a}-1,3,5-triazinones (1) which are analogues of N(9)-substituted guanines, hypoxanthines, and xanthines. Structures were established in this series (1) on the basis of precursors and routes of synthesis, infrared spectra, mass …

Patterns of somatic genome rearrangement in human cancer
… of one or more chromosomes. Studies of somatic rearrangement have previously been limited by a paucity of whole genome sequencing data, and a lack of methods for comprehensive structural classification and downstream analysis. The ICGC project on the Pan-Cancer Analysis of Whole Genomes provides …
