5264-35-7, Name is 5-Methoxy-3,4-dihydro-2H-pyrrole, belongs to pyrrolines compound, is a common compound. category: pyrrolinesIn an article, once mentioned the new application about 5264-35-7.
tert-Butylcyclopentane derivatives. Part 8. Synthesis of tert-butylcyclopentane-fused pyrimidin-4-ones
In the reactions of ethyl (1R*,2S*,45*)-2-amino-4-tert-butyl-1-cyclopentanecarboxylate (4) or (1R*,3S*,5S*)-3-tert-butyl-6-azabicyclo[3.2.0]heptan-7-one (2) or (1R*,2S*,4S*)-2-amino-4-tert-butyl-1-cyclopentanecarboxamide (6) with imidates or triethyl orthobenzoate, tert-butylcyclopentane-fused dihydropyrimidin-4-ones (7a-e) were prepared. The azetidinone (2) with lactim ethers furnished pyrrolo-, pyrido- and azepino[1,2-a]pyrimidin-4-ones (8-10) in ring-enlargement reactions. Ethyl (1R*,2S*,4S*)-2-amino-4-tert-butyl-1-cyclopentanecarboxylate (4) and ethyl (1R*,2S*,4S*)-2-benzylamino-4-tert-butyl-1- cyclopentanecarboxylate (5) and potassium cyanate or phenyl isocyanate or potassium thiocyanate or phenyl isothiocyanate, yielded pyrimidine-2,4-diones or 2-thioxopyrimidin-4-ones (11-22).
