Rearrangement of oxazolo[3,2-a]pyridines as an approach of synthesizing aza[3.3.2]cyclazines
摘要:
[GRAPHICS]5-Methyloxazolo[3,2-a]pyridinium salts were shown to react with (methylamino)acetaldehyde dimethyl acetal leading to the formation of functionalized 5-aminoindolizines, which in turn are capable of closing the pyrimidine ring in acidic media forming aza[3.3.2] cyclazines.
