, p. 459 - 462 (2001)
A convenient preparative method has been developed for obtaining previously unknown 4-(o-hydroxyphenoxy) substituted pyrazoles by the reaction of (Z)-3-acetyl-2-methyl-2,3-dihydro-1,4-benzodioxin-2-ol with hydrazine.
ACYLOTROPIC REARRANGEMENT OF o-ACYLOXYPHENOXYACETONES
Dzvinchuk, I. B.,Lozinskii, M. O.
, p. 1146 - 1152 (2007/10/02)
A new type of intramolecular ester Claisen condensation, i.e., the alkali-catalyzed O,C--acylotropic rearrangement of o-acyloxyphenoxyacetones, is described.The reaction leads to the products from intramolecular cyclization or alkaline hydrolysis of
