标题 :Synthesis of amino hydroxy cyclopentenones

摘要:This invention relates to a method of synthesizing 3-amino-2-hydroxy-2-cyclopentenones possessing an aliphatic substituent in the 4-position which comprises reacting cyanoacetamide with an aliphatic aldehyde to yield the corresponding β-substituted-α,α'-dicyanoglutaramide, hydrolyzing the amide to the corresponding β-substituted glutaric acid, esterifying the acid to the corresponding dialkyl diester, converting the diester to a 1,2-bis(trimethylsiloxy)-4-substituted cyclopentene by reductive cyclization using chlorotrimethylsilane in the presence of sodium, hydrolyzing and oxidizing the bis(trimethylsiloxy) compound to the 2-hydroxy-4-substituted-2-cyclopentenone in the presence of a cupric salt, nitrosating the 2-cyclopentenone to the 2-hydroxy-4-substituted-5-oximino-2-cyclopentenone, converting the oxime to the 2-acetoxy-3-amino-4-substituted-2-cyclopentenone by reductive acetylation and removing the acetyl group by alkanolysis to yield the 3-amino-2-hydroxy-4-substituted-2-cyclopentenone product.
