QUINOLIZIDINES. XXIII. AN ALTERNATIVE SYNTHETIC ROUTE TO BENZOQUINOLIZIDINE-TYPE ALANGIUM ALKALOIDS FROM ETHYL CINCHOLOIPONATE

The trans lactam acid (+)-XX was isolated in good yield in the form of the 4-methoxybenzyl ester (+)-XXV from an equilibrated 66:34 mixture of the trans and cis isomers , which was obtained by thermal cis-trans isomerization of the cis
