8H-ANHYDRO-4-HYDROXY-2-OXO-1,3-THIAZINUM HYDROXIDES AS MESOIONIC 1,4-DIPOLES

, p. 1631 - 1652 (2007/10/03)
The previously unknown 8H-anhydro-4-hydroxy-2-oxo-1,3-thiazinum hydroxides (1) were prepared and their 1,4-dipolar cycloaddition behavior was examined.In most cases, elimination of the proton in the 8-position of the mesoionic ring was observed to occur unless extremely reactive dipolarophiles were used.The S,N-ketene acetals were converted to the corresponding α-diazo ketones for further study.
