Treatment of benzothiazines 3 and 8 with butyllithium resulted in deprotonation at C3 to afford the corresponding organolithium species. These compounds could be trapped with a variety of electrophiles to give products in high yield. Some limitations to the processes chiefly based on steric effects were uncovered. Interesting and potentially useful side reactions were also established. Georg Thieme Verlag Stuttgart. New York.
