Asymmetric dihydroxylation of intermeddiate silylated olefin (XII) employing potassium ferricyanide in the presence of osmium tetraoxide and the chiral auxiliary hydroquinidine 1,4-phthalazindiyl diether produced diol (XVIII). After conversion of the primary hydroxyl group of (XVIII) to the corresponding tosylate (XIX), displacement with ethanolamine yielded hydroxy amine (XX). Protection of (XX) as the Boc derivative (XXI), followed by cyclization under Mitsunobu conditions gave rise to morpholine (XXII). The Boc and silyl groups of (XXII) were then deprotected with HCl in dioxan, and the deprotected morpholine (XXIII) was acylated with 3,4,5-trimethoxybenzoyl chloride (XXIV) to produce amide (XXV). The alcohol group of (XXV) was then converted to mesylate (XXVI) using methanesulfonyl chloride and triethylamine. Optionally, the alchohol group was subjected to Swern oxidation, affording aldehyde (XXVII).
