Abstract
This Letter describes the synthesis of challenging pyridyl analogues of 3-oxo-3,4-dihydro-2H-1,4-(benzothiazine or benzoxazine)-6-carbaldehydes. The six different routes described are high yielding, contain no major purification issues and have been used to give gram quantities of each aldehyde.
