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. (C) 2010 Elsevier Ltd. All rights reserved.
