Versuchsvorschrift
In a similar manner to the procedures described in. Preparative Examples 8(ii)′, 8(iii)′, 8(iv)′, 8(v)′ and 8(vi)′ above, reactions were conducted in turn, using (S)-1-benzyloxycarbonyl-4-ethylideneproline methyl ester [prepared as described in Preparative Example 24′ above] instead of (S)-1-benzyloxycarbonyl-4-methylideneproline methyl ester, to give the title compound as a brown oil (yield: 10%).
