A series of diazabicyclic derivatives were prepared in three to four steps from p-anisidine and p-nitrobenzaldehyde. The key step of the synthesis involved the acid-catalyzed coupling of 4-aminocoumarin or dimedone derivatives with amino alcohols 3 or 7 t

(Chemical Equation Presented) A new photochromic colorant with an oxazabicyclic moiety has been synthesized by an efficient method. It turns pale red upon UV irradiation and undergoes reverse reaction while being heated. This work may open an exciting new

This work describes the efficient synthesis of functionalized cleft molecules 6, 6a, 16, 16a, 17, 19 and 20 derived from benzopyrano[4,3-d][1,3] benzooxazocin-13-one. X-ray crystal structure analysis of compounds 6a and 16a revealed that the cleft angles of the planes of the benzopyran moiety and the p-methoxybenzene ring are 109.4° and 108.6°, respectively. The conformation of the aromatic ring at the bridgehead of 16, 16a and 20 is restricted by the gem-dimethyl groups on the C-9 position and the methyl group on the nitrogen atom in the ring.
