Cyclohexadienones participate in a two-step procedure, a Michael addition followed by aromatization, providing hitherto difficult-to-synthesize meta-functionalized phenol derivatives in good yield. Application of the developed approach is exemplified by synthesizing C-aryl acetophenones, C-aryl glycines, and elemicin - an allylphenol natural product. Georg Thieme Verlag Stuttgart · New York.
Electronic effects of ring substituents on triplet benzylic biradicals
Wagner, Peter J.,Wang, Lingling
, p. 645 - 647 (2007/10/03)
UV irradiation of α-(o-alkylphenyl)acetophenones with a methoxy or cyano substituent para to the o-alkyl group of the α-aryl ring has revealed that a methoxy group slightly increases the stereoselectivity but not the quantum yield of indanol formation, whereas a cyano group greatly lowers both diastereoselectivity and quantum efficiency, confirming the likelihood that hydrogen-bonding of the hydroxy group to the α-phenyl ring plays an important role in the cyclization of the photogenerated triplet 1,5-biradical intermediates.
