On the Reaction of 1,3-Oxazolidines with Dicarboxylic Acid Anhydrides
Reaction of 3-methyl-1,3-oxazolidine with phthalic anhydride in chloroform leads to ring opening and higher oligomers 2 are formed.These are cleaved by addition of protic solvents and 2-methylaminoethyl hydrogenphthalate 3a is obtained.Other 1,3-oxazolidines and succinic anhydride behave similarly. - Keywords: Acid anhydrides; 1,3-Oxazolidines; Phthalic anhydride, reaction with 1,3-oxazolidines
