The electron withdrawing capacity of the nitrile group can be used to a series of syntheses of ring enlarged lactones in high yields [97] [98] [99]. For example, the preparation of 12-methyl-15-pentadecanolide (VII/143) from l-(2-formyl-ethyl)-2-oxocyclododecane-l-carbonitrile (VII/139) is summarized in Scheme VH/28 [99]. [Pg.150]
