, p. 3526 - 3530 (2021/06/12)
An efficient approach to functionalized 4,6-disubstituted-and 4,6,6-trisubstituted-1,3-oxazinan-2-ones skeleton has been developed through the reaction of semicyclic N,O-acetals 4a and 4b with 1,1-disubstituted ethylenes 5 or 8. As a result of such a [4 +

Reduction of N-alkyl-2-(2-hydroxy-2-phenylethyl)pyridinium salts using excess of sodium triacetoxyborohydride afforded exclusively the corresponding tetrahydropyridine derivative bearing a piperidine ring with a double bond in the 3,4-position. Furthermore, under these conditions, syn-1,3-amino alcohols were obtained in good yield and diastereoselectivity. Georg Thieme Verlag Stuttgart · New York.
Enantioselective synthesis of lobeline via nonenzymatic desymmetrization
Birman, Vladimir B.,Jiang, Hui,Li, Ximin
, p. 3237 - 3240 (2008/02/11)
Lobeline has been prepared in enantiopure form via desymmetrization of lobelanidine with use of BTM, a nonenzymatic enantioselective acyl transfer catalyst.
