Transformations Starting from Biotechnologically Available Materials, Part 2: First Example of a Direct Conversion of Spirooxiranes into Enamines
Svetlik, Jan
, p. 145 - 150 (2007/10/02)
An unpredecent formation of enamines in the reaction of 5-aryl-1-oxa-5-azaspiroheptane-4,6-diones with morpholine and piperidine is reported.The transformation proceed via corresponding β-aminoalcohols which were detected by 13C-NMR.Keywords: Enamines; Nucleophilic ring opening; Spirooxiranes.
AMINO- AND THIOMETHYLENATION OF MALEIMIDES
Abramovitch, Rudolph A.,Floch, Lubomir
, p. 391 - 394 (2007/10/02)
Reaction of pyridinium p-toluenesulfonylmethylide with N-substituted maleimides in the presence of primary or secondary amines gives aminomethylenesuccinimides (4).The geometry of these enamines is presented.In one case, the E- and Z-isomers have been sep
