Diels‐Alder Reactions of 2,4‐Bis{[( tert ‐Butyl)dimethylsilyl]oxy}‐3‐aza‐‐1,3‐pentadien with Heterodienophiles The 2,4‐bis{[( tert ‐butyl)dimethylsilyl]oxy}‐3‐aza‐1,3‐pentadien( 2 ) reacts via the Diels‐Alder adducts 3 , 6a‐c , and 8a , b , which cannot be isolated, giving the triazines 4 , 7a‐c , and the oxadiazines 9a , b . The hydrolysis of 4 in MeOH affords the N ‐acetyl‐acetamid derivative 5 . The formula of 9a is proven by an X‐ray‐structure analysis.
