1) The reaction of cis-(1S,2R)-indanediol (I) with acetonitrile and concentrated H2SO4 gives cis-(1S,2R)-1-aminoindan-2-ol (II), which is cyclocondensed with 3-phenylpropionyl chloride (III), isopropenyl methyl ether and triethylamine to yield the acetonide amide (IV). The condensation of amide (IV) with (S)-(+)-glycidyl p-toluenesulfonate (V) in the presence of lithium hexamethyldisylazide (LHS) affords the chiral epoxide (VI), which is condensed with 4-(tert-butoxycarbonyl)-N-tert-butylpiperazine-2(S)-carboxamide (VII) in refluxing isopropyl acetate and deprotected with aqueous HCl to give the dihydroxy-diamide (VIII). Finally, this compound is condensed with 3-(chloromethyl)pyridine (IX) by means of triethylamine in DMF. 2) The amide (IV) can also be alkylated with allyl bromide and butyllithium to the pentenyl amide (X), which is diastereoselectively converted to the chiral iodohydrine (XI) by means of N-iodosuccinimide (NIS). Finally, this compound is cyclized in basic medium, yielding the epoxide (VI), already obtained.
