Mj. Bassindale et al., Employment of a cyclobutene ring-opening metathesis reaction towards a concise synthesis of (+/-)-sporochnol A, TETRAHEDR L, 42(51), 2001, pp. 9055-9057
A concise formal synthesis of (+/-)-sporochnol A 1, a naturally occurring f
eeding deterrent towards herbivorous fish, is described. The target compoun
d was prepared by the employment of a Ru-catalysed cyclobutene ring-opening
metathesis reaction with gaseous ethylene followed by a site selective hyd
roboration reaction as the key steps. The optimisation of the metathesis pr
ocess regarding the Ru-catalyst and reaction conditions is also delineated.
