New Advances in Chemical Research in 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis,and research on the structure and performance of functional materials. 3034-86-4, Name is Methyl 4-ethynylbenzoate, molecular formula is C10H8O2, belongs to isothiazole compound. In a document, author is Assy, MG, introduce the new discover, Product Details of 3034-86-4.
Isothiocyanate 1 reacted with enaminone 2 to give thioamide 3 that cyclized by sodium hydroxide to pyrimidine 4 but cyclized by bromine to give isothiazole 5, pyrimidine 4 was transformed into thiopyranopyrimidines 7, 9 or 11 upon respective reaction with benzaldehyde, maleic acid, or maleic anhydride. Aminative cyclization of 4 yielded isothiazolopyrimidine 13. Reaction of 4 and ethyl bromoacetate or phenacyl bromides afforded thienopyrimidines 15a-b respectively. Oxidation of 4 yielded oxopyrimidine 16.
Each elementary reaction can be described in terms of its molecularity, the number of molecules that collide in that step. If you are hungry for even more, make sure to check my other article about 3034-86-4, Product Details of 3034-86-4.
