Synthesis of pyrrole N-derivatives from oxazolidines
Sadykov, E. Kh.,Stankevich,Lobanova,Klimenko
, p. 219 - 224 (2014/04/17)
Transformations of oxazolidine derivatives synthesized from industrially produced amino alcohols, aldehydes, and ketones under basic or acidic catalysis lead to the formation of N-alkyl- and N-(hydroxyalkyl)-substituted pyrroles in 19-81% yields.
Chemodivergent synthesis of 7-aryl/alkyl-6-hydroxy-1,4-oxazepan-5-ones and 2-[aryl/alkyl(hydroxy)methyl]morpholin-3-ones from a common epoxyamide precursor

We present here a regiospecific synthesis of 7-alkyl- or 7-aryl-6-hydroxy-1,4-oxazepan-5-ones and 2-[aryl(hydroxy)methyl]- or 2-(1-hydroxyalkyl)morpholin-3-ones from a diastereomeric mixture of trans-3-alkyl- or -3-aryl-N-(2-hydroxyethyl)-N-(1-phenylethyl)oxirane-2- carboxamides. This chemodivergent synthesis is easily controlled by an appropriate choice of cyclization reaction conditions. Georg Thieme Verlag Stuttgart - New York.
Practical asymmetric preparation of azetidine-2-carboxylic acid
Couty, Francois,Evano, Gwilherm,Vargas-Sanchez, Monica,Bouzas, Gloria
, p. 9028 - 9031 (2007/10/03)
Facile and straightforward syntheses of both enantiomers of azetidine-2-carboxylic acid are described. The syntheses depart from inexpensive chemicals and allow for the production, in five to six steps, of practical quantities of each enantiomer. Synthetic highlights include the construction of the azetidine ring using an intramolecular alkylation and the use of optically active α-methylbenzylamine as chiral auxiliary.
