West, F. G.'s team published research in Journal of Organic Chemistry in 59

West, F. G. published the artcileApplications of Stevens [1,2]-Shifts of Cyclic Ammonium Ylides. A Route to Morpholin-2-ones, Synthetic Route of 101-98-4, the publication is Journal of Organic Chemistry (1994), 59(20), 6051-6, database is CAplus.

2-(N,N-Dialkylamino)ethyl diazoacetoacetates I (R¹ = benzyl, alkyl, etc.; R² = Me, benzyl) were prepared in two steps from ethanolamines. When heated in the presence of catalytic Cu, the substrates cleanly formed morpholinones II (same R¹, R²), presumably via the intermediacy of copper carbenoids and cyclic ammonium ylides. In most cases involving benzylic or allylic migrating groups, ylide [1,2]-shift occurred in good yield (55-80%). Simple alkyl groups failed to undergo the rearrangement, with the exception of a tert-Bu substituted compound, which furnished morpholinone II (R¹ = tert-Bu, R² = Me) in 10% yield.

Journal of Organic Chemistry published new progress about 101-98-4. 101-98-4 belongs to alcohols-buliding-blocks, auxiliary class Amine,Benzene,Alcohol, name is 2-(Benzyl(methyl)amino)ethanol, and the molecular formula is C17H16O2, Synthetic Route of 101-98-4.
