Abstract
Abstract Dibutyl zirconocene-mediated trans-selective cyclization of methoxyallyl-ene followed by the reaction with electrophiles is a convenient method for the synthesis of functionalized cyclopentane derivatives. Ring-closing metathesis of the obtained cyclopentane derivative yielded a common building block for the synthesis of sesquiterpene analogues with unnatural trans-[3.4. 0] bicyclo-nonane skeleton.
