Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. Formula: C17H14O,
New 6-amino and 6,8-diamino-2-aryl-2,3-dihydro-4-styryl-1H- pyrimido[4,5-b][1,4]diazepines were obtained in the reaction of 2,4,5,6-tetraaminopyrimidine 1a and 4,5,6-triaminopyrimidine 1b with one equivalent of the diarylideneacetones 2 in absolute ethanol with acetic acid as the catalyst. Structure analysis of 6-amino and 6,8-diamino-2-aryl-2,3-dihydro-4-styryl-1H- pyrimido[4,5-b][1,4]diazepines 3a-i, determined by detailed nmr measurements, reveals a high regioselectivity of this reaction.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 538-58-9 . Formula: C17H14O
