A new procedure for functionalization of the dihydroazulene photoswitch on its seven-membered ring was developed, which has allowed isolation of the first dihydroazulene with a phenyl substituent at position 5 from a mixture of regioisomers. Light-induced ring-opening to the corresponding vinylheptafulvene and the thermal back-reaction was studied in detail.
开发了一种在其七元环上对二氢吖啶光开关进行功能化的新方法，该方法允许从区域异构体混合物中分离出第一个在 5 位带有苯基取代基的二氢吖啶。详细研究了光诱导开环至相应的乙烯基庚富烯和热逆反应。
