5. Synhtetic schemes below
(a) Is prepared by oxidation of alcohol, protection by 1,2-dithiol and deprotection of other carbonyl. Coupling with grignard gives the product.
(b) Is prepared by free radical bromination, followed by hydrolysis and oxidation. alpha-alkylation and then aldol type reaction gives the product.
(c) Is prepared by 3 moles of benzene alkylated and oxidized to acid. esterification with glycerol yields the product.
