A simple one-pot domino reaction procedure for the stereoselective synthesis of oxazolidines and C2-symmetric pyrrolidines from inexpensive starting materials is described. Azomethine ylides generated in situ by heating a mixture of benzaldehyde and benzylic amines are trapped with dipolarophiles by a 1,3-dipolar cycloaddition reaction. The products represent valuable synthetic building blocks or potential starting materials for the preparation of chiral auxiliaries and are difficult to obtain by other methods.
AZIRIDINES-IV CATALYTIC DECOMPOSITION OF PHENYLDIAZOMETHANE IN SCHIFF'S BASES
Bartnik, R.,Mloston, G.
, p. 2569 - 2576 (2007/10/02)
Catalytic decomposition of phenyldiazomethane in Schiff's bases is found to proceed via formation of trans-1,3-dipole (azomethine ylide) as an intermediate product.Depending on the size and quantity of the substituents, the ylide undergoes either cyclizat
