Resumen
A six-step semisynthetic approach towards chiral nonracemic pyrrolo-allocolchicinoids starting from naturally occurring colchicine was developed. The synthetic scheme includes an electrocyclic tropolone ring contraction to afford allocolchicinic acid followed by the Curtius reaction, giving the corresponding aniline. The Sandmeyer reaction and copper-mediated hydrazination gave hydrazine-substituted allocolchicine. This was introduced into the Fischer indole synthesis, affording libraries of regioisomeric indole-based allocolchicine congeners.

Resumen
Based on the natural antimitotic agent colchifoline as a lead structure, a series of novel bifunctional allocolchicine congeners were synthesized from commercial colchicine. The new derivatives maintain good cytotoxicity against T3M4, MiaPaCa-2, and PANC-1 cell lines. The presence of functional groups simplifies further modifications of the prepared structures and the design of novel colchicine-derived antitumor compounds with desired pharmacological properties.

Resumen
Abstract A concise formal synthesis of racemic allocolchicine has been developed, centred on three principal transformations: a retro-Brook alkylation reaction to generate an arylsilane, a gold-catalysed arylative cyclisation to generate the B-ring via biaryl linkage, and a palladium-catalysed carbonylation of an aryl chloride to generate an ester. 1H NMR monitoring of the key gold-catalysed cyclisation step reveals that a powerful catalyst deactivation process progressively attenuates the rate of catalyst turnover. The origins of the catalyst deactivation have been investigated, with an uncatalysed side-reaction, involving the substrate and the iodine(III) oxidant, identified as the source of a potent catalyst poison. The side reaction generates 1–4% of a diaryliodonium salt, and whilst this moiety is shown not to be an innate catalyst deactivator, when it is tethered to the arylsilane reactant, the inhibition becomes powerful. Kinetic modelling of processes run at two different catalyst concentrations allows extraction of the partitioning of the gold catalyst between the substrate and its diaryliodonium salt, with a rate of diaryliodonium salt generation consistent with that independently determined in the absence of catalyst. The high partition ratio between substrate and diaryliodonium salt (5/1) results in very efficient, and ultimately complete, diversion of the catalyst off-cycle. Graphical Abstract
