Zhou, You published the artcileI2-Promoted site-selective C-C bond cleavage of aryl methyl ketones as C1 synthons for constructing 5-acyl-1H-pyrazolo[3,4-b]pyridines, COA of Formula: C7H13NO2, the publication is Organic Chemistry Frontiers (2022), 9(16), 4416-4420, database is CAplus.
A novel iodine promoted [1 + 3 + 2] cleavage cyclization reaction for the synthesis of 1H-pyrazolo[3,4-b]pyridines from aryl Me ketones, 5-aminopyrazoles and enaminones was established. This transition metal-free catalysis method has simple reaction conditions and good substrate compatibility, and was demonstrated in the transformation of alkyl and natural mol.-derived enaminones. Mechanistic studies showed that two cyclization pathways affording different key intermediates were involved, but affording the same target product after site-selective cleavage of the unstrained C-C bond of the acyl group.
