Yn. Ogibin et al., PREPARATION OF 2-(6-CARBOXYHEXYL) AND 2-(6-METHOXYCARBONYLHEXYL)CYCLOPENT-2-EN-1-ONE USING FREE-RADICAL REACTIONS, Synthesis, (9), 1994, pp. 901-903
Two short and simple synthetic routes to the prostaglandin synthons 2-
(6-carboxyhexyl)- and 2-(6-methoxycarbonylhexyl)cyclopent-2-en-1-one h
ave been developed. The first is based on a cyclohexanone oxidative tr
ansformation with hydrogen peroxide and di-tert-butyl peroxide, the se
cond on the free radical addition reaction of methyl 9-oxononanoate to
acrylaldehyde diacylal.
