Synthesis of substituted cyclopentanones from 6-methylhept-5-en-2-one
摘要:
Readily available tert-butyl- and phenyl sulfoxide derivatives of methylheptenone were converted by the Pummerer method to the corresponding five-membered keto sulfides which are probable precursors of iridanes and related terpent cyclopentanoids.

give α-phenylsulfinyl ketones directly, together with minor amounts of α-phenylsulfanyl ketones. These are easily separated by forming the water-soluble sodium salts of the sulfinyl compounds. Grignardreagents also react with phenyl benzenethiosulfinate, to give mixtures of sulfoxides and sulfides.
