2, oxazoles were used as intermediates in a new method for preparation of Nl-methyl-3-hydroxypyrazoles. Synthesis of this bicyclic system was achieved either by alkylation of 3-hydroxypyrazole with 1,2-dibromoethane or, with better yields, by cyclization of l-tosyl-2-(2-hydroxyethyl)pyrazol-3-ones
The synthesis of a new series of hydroxypyrazoles (2a-f) and 2-methyl-3-isoxazolones (3a-d) from the cyclocondensation reaction of trichloromethyl-substituted 1,3-dielectrophiles (1a-f) with dry hydrazine and N-methylhydroxylamine is reported. The regiospecific cyclocondensation took place with the
