The synthesis of ( )-7-ACA 81a is shown in Scheme 19. Reaction of 77 with 4-nitrobenzaldehyde followed by treatment with Hilnig s base gave a 2 3 mixture of cis/trans isomers of the Schiff base 79. Compound 79 was therefore cleaved with Girard s reagent T and amines 77 and 80 were obtained after chromatography. Amine 80 was converted to ( )-7-ACA 81a as outlined below. [Pg.138]
