CYCLOPENTANOIDS FROM PHENOL-9 3-ALKYL- AND 3-ALKENYL-5-HYDROXYCYCLOPENT-2-ENONES

An efficient and versatile synthesis of 3-alkyl- and 3-alkenyl-5-hydroxycyclopent-2-enones is described.The key intermediate, 4-(t-butyldimethylsilyloxy)-3-methoxycyclopent-2-enone (5), is prepared in five steps from phenol. 1,2-Addition of various organolithium and Grignard reagents yields tertiary alcohol intermediates which afford the title compounds after solvolysis and desilylation.
