A novel approach to the synthesis of regular monocyclopentanoids of the sesquiterpene series
摘要:
A five-step scheme has been developed for the construction of the regular sesquiterpene cyclopentanoid skeleton characteristic of the metabolites of several species of fungi, based on trans-3-isopropenyl-2-phenylsulfonylcyclo-pentan-1-one, readily accessible from methylheptenone.
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.
