Abstract
The bis-allylic 1 and the bis-propargylic 6 derivatives react with the zirconocene ''ZrCp(2)'' and lead, after electrophilic addition, to th e corresponding chiral trans heterocyclopentanes (M=Si,Ge,P) 3-5 and b is-methylenecyclopentanes 8. New chiral diphosphine 9 is obtained star ting from the intermediate complex 2 or the functionalized heterocyclo pentane 4. Copyright (C) 1996 Elsevier Science Ltd
