Syntheses of Anisomycin Derivatives
The structure of anisomycin has been determined by X-ray investigation4 and the absolute configuration was confirmed by chemical correlation.5 Anisomycin has attracted considerable synthetic interest, and several synthetic studies, derivative syntheses as well as total syntheses, have been reported.6 Especially, the synthesis of its analogues has revealed the structure-activity relationship of ...

متن کاملConvenient syntheses of fullerynes for ‘clicking’ into fullerene polymers
Alkyne-functionalized fullerenes (fullerynes) were designed and conveniently synthesized via Bingel reaction in one step with high yields. They were used to react with azido-functionalized polystyrene (PS) via Huisgen [3 + 2] cycloaddition 'click' chemistry to form two fullerene polymers: one with C60 tethered to the end of a PS chain (C60-1PS) and the other with C60 tethered at the junction po...
متن کاملA Convenient Synthesis of 3,7'-Bisindole Derivatives.
An efficient and convenient method to synthesize highly functionalized 3,7'-bisindole derivatives has been developed via a Michael addition and cyclic condensation reaction of heterocyclic ketene aminals (HKAs) with 2-(1H-indol-3-yl)cyclohexa-2,5-diene-1,4-dione derivatives in ethanol-based solvents at room temperature. This strategy provides an efficient, environmentally friendly approach for ...
متن کاملMicrowave-Assisted Convenient Syntheses of 2-Indolizine Derivatives from Morita-Baylis-Hillman Adducts: New in silico Potential Ion Channel Modulators
Neste artigo, um estudo sintético assistido por irradiação de micro-ondas para produzir 2-indolizina-carbonitrila e 2-indolizina-carboxilato de metila em bons a altos rendimentos (70 e 81%) em uma etapa a partir de adutos de Morita-Baylis-Hillman (AMBH) é apresentado. Estes compostos foram subsequentemente transformados em altos rendimentos (94-100%) em três derivados 2-indolizínicos. Os cinco ...
