Fluorinated acyl‐Meldrum’s acid derivatives were synthesised by electrophilic fluorination of appropriate phenacyl Meldrum’s acid substrates using Selectfluor. Reactions with water, ethanol, Grignard and alkynyl lithium reagents gave rise to the corr...

Tetrahydropyrido 3,4-b pyrazine scaffolds from pentafluoropyridine (2005)
Journal Article
Sandford, G., Slater, R., Yufit, D., Howard, J., & Vong, A. (2005). Tetrahydropyrido 3,4-b pyrazine scaffolds from pentafluoropyridine. Journal of Organic Chemistry, 70(18), 7208-7216. https://doi.org/10.1021/jo0508696

Representative polyfunctional tetrahydropyrido[3,4-b]pyrazine scaffolds have been synthesized very readily by a one-pot annelation reaction of pentafluoropyridine with appropriate diamines. The trifluorinated pyridopyrazine products react sequentiall... Read More about Tetrahydropyrido 3,4-b pyrazine scaffolds from pentafluoropyridine.
