Abstract

Ring-chain tautomerism involving the reversible addition of a heteroatom to a heteropolar double bond'is a well-established process for 1, 3-0, N-hetero~ ycles.~ J Particular attention has been paid to the tautomerism of 1, 3-0xazolidines,~~ which contrasts to Baldwin's rules. 8 In spite of the interest in this ring system, few papers5 describe the quantitative determination of the ring-chain equilibria. The pioneering work by Paukstelis and ...
