Alkylation of the substituted cycloalkanones 14a–d and 30 with (Z)-1-bromo-4-methyl-3-trimethylstannyl-2-pentene (13) produced compounds 15a–d and 33, which were readily converted into the correspo...

Alkylation of cyclic ketones and α-methoxycarbonyl ketones with 4-iodo-2-trimethylstannylbut-1-ene and/or 5-iodo-2-trimethylstannylpent-1-ene, and subsequent (Ph3P)4Pd-catalysed cyclization of the enol trifluoromethanesulphonates derived form the alkylation products, from the basis of new annulationsequences which result in the formation of dienesystems.
