N-Nitrosation of (E)-(S)-2-(benzylidene-amino)ethanols 2 with nitric oxide occurred highly diastereoselectively, to give the (2S,4S)-diastereomer dominant N-nitroso-(2S,4S)-1,3-oxazolidines in good yield. Intermediate 2 was prepared from the reaction of b

(2R,3R,5R)-2-Aryl-3,5-diphenyl-[1,4,2]-oxazaphosphinanes 6, analogues of C-arylmorpholinol 3, were prepared with diastereomeric excess higher than 94%, via a three step sequence: (i) diastereoselective addition-cyclization reaction from methyl hypophosphi

Diastereoselective reactions between (S)-phenylglycinol-derived oxazolidines and two unsaturated organolithium reagents afforded chiral β-amino alcohols having vinyl and alkynylsilane moieties. When the same reactions were performed in the presence of titanium isopropoxide, a dramatic change of regioselectivity was observed, from the α- to the γ-position, thus producing β-amino alcohols with allyl or allenylsilane functions. A rationalization of the observed diastereoselectivity was suggested for each case.
Dramatic change of regioselectivity in the addition of silylated organolithium reagents with oxazolidines induced by the presence of a titanium salt

Diastereoselective reactions between oxazolidines and organolithium reagents afford β-amino alcohols having chiral vinyl and alkynylsilane moieties. A meaningful change of regioselectivity, from the α- to the γ-position, occurred when these reactions were
A stereoselective concise synthesis of C2- and meso-aminodiols from (R)-phenylglycinol
Scialdone, Mark A.,Meyers
, p. 7533 - 7536 (2007/10/02)
Oxazolidines derived from (R)-phenylglycinol can undergo diastereoselective vinyl- and aryl addition to give, after oxidative cleavage, meso- and C2-diethanol amines.
