The benzyl adducts are also obtained in the photochemical reactions with other carbonyl compounds [1-NA, l -acetonaphthone (1-AN), 2 -aceto-naphthone (2-AN)] in the presence of Mg2+ in MeCN [188], When benzyltrimethylsilane is replaced by allyltrimethylsilane (CH2=CHCH2 x SiMe3), the corresponding allyl adducts are also obtained [188],...

The photocycloaddition of 2-morpholinoacrylonitrile to substituted 1-aceto-naphthone (62) has been found to be substituent-dependent. For example, (62 R = MeO, R = H) gives only the [4+2] cycloadduct whereas (62 R = H, R = CN R = H, R = MeO) lead to the [2+2] cycloadduct. The calix[4]arene-based 2-naphthoate (63) is reported to be photoconverted into the dimer (64), and photocycloreversion of the cyclodimers (65 - 69) gives quantitative yields of the corresponding naphthalenes. ... 

In addition, Schiff bases can also be applied as intermediates of quinoline formation. Thus, Schiff bases derived from 2-(trifluoromethyl) aniline and a methyl naphthone, mediated by lithium 2-(dimethylamino)-ethylamide, were used to furnish a series of substituted 2-(2-naphthyl)quinolines designed to target DNA. ... 

The 2-naphthonate moiety is most likely of polyketide origin, but the exact nature of the nascent linear polyketide intermediate and its subsequent folding pattern to afford the 2-naphthonate backbone cannot be predicted in the absence of isotope labeling experiments. Since the biosynthesis of 1-naphthoic acid moiety in 301 is catalyzed by the iterative type I PKSs, and a close examination of the oifs within the 302 cluster identified, in addition to kedE that encodes the enediyne PKS, kedU38 that resides in the middle of the 15-gene type I PKS locus and encodes a type I PKS with a similar domain organization as in 301, it was proposed that KedL138 catalyzes the formation of a nascent intermediate, which is further modified by the other activities within the type I PKS locus to yield 3,6,8-trihydroxy-2-naphthoic acid as a key intermediate. 

Only a few examples of substrate-controlled diastereoselective intramolecular oxidative dearomatization have appeared. These transformations are analogous to the reaction shown in Scheme 15.20 in that stereogenic centers present on the linker connecting the carbon nucleophile to the arene substrate are responsible for diastereoselectivity [69, 70]. A rare example of a true metal-catalyzed oxidative dearomatization of substituted 2-naphthols is shown in Scheme 15.25. Treatment of naphthol 67 with Fe(salen) catalyst 68 in the presence of nitromethane (as a carbon nucleophile) and air (O as stoichiometric oxidant) gave naphthone 69 possessing a quaternary carbon center in 90% ee [71].

When carried out in kerosene medium, the carbonation occurs in a three-phase system in which CO2 first dissolves in the liquid and then diffuses to the solid naphthonate present as a particulate suspension in the liquid. Since the solid is insoluble in kerosene, reaction occurs only in the solid phase. Using the data of Phadtare and Doraiswamy (1965, 1969), reproduced in Table E12.2.1, formulate a model to predict the conversion of sodium naphthonate to BON acid as a function of time.

Aryl ketones were found to be excellent substrates for this transformation, with naphthone resulting in the highest enantioselectivity of 92%. The nature and position of the substituent on the aromatic ring had little effect on the enantioselective outcome of the reaction. Methallyl and crotylbromide were successfully added to acetophenone with very good enantioselectivities reported, although the addition of crotylbromide resulted in a modest diastereoselectivity.
