RING-CHAIN TAUTOMERISM OF 1,3-OXAZOLIDINES PREPARED FROM NOREPHEDRINE AND NORPSEUDOEPHEDRINE

The reactions of norephedrine and norpseudoephedrine with eleven different arometic aldehydes led, in each case, to tautomeric equilibria consisting of two ring and one open-chain forms and obeying the equation: log KX = p?+ + c, whe
