A series of methoxy-substituted 2,2-di(4-methoxyphenyl)-2H-naphtho[1,2-b]pyrans has been synthesised from 3-alkoxycarbonyl-1-naphthols and 1,1-di(4-methoxyphenyl)prop-2-yn-1-ol. The influence of the methoxy group on the wavelength of maximum absorption an
An efficient method for the synthesis of substituted 4-acetoxynaphthalene- 2-carboxylate esters, ethyl 4-acetoxybenzofuran-6-carboxylate, and ethyl 4-acetoxybenzothiophene-6-carboxylate

4-Acetoxynaphthalene-2-carboxylate esters and their corresponding benzofuran and benzothiophene esters are important synthetic intermediates for the preparation of analogs of CC-1065 and the duocarmycins. In this communication, an efficient method for the synthesis of the titled compounds using an Emmons-Horner reaction strategy is reported. As an alternative to the Stobbe condensation reaction, coupling of tert-butyl 3-ethoxycarbonyl-3- (phosphonodiethyl)propionate with a series of aromatic aldehydes, followed by acid promoted removal of the tert-butyl group and Friedel-Crafts reaction, produced the target compounds in good overall yields and of excellent quality.
Studies on the Synthesis of highly substituted naphthol: Preparation of 6-Hydroxy-5,7-Dimethoxy-2-Naphthoic Acid, Isolated From Ulmus Thomasii

An improvement of a known procedure, affording substituted 4-hydroxy-2-naphthoic acid derivatives from aromatic aldehydes is described and its general applicability is shown through the preparation of a natural naphthalene derivative isolated from Ulmus thomasii.
tert-Butyl-3-carboxyethyl-3-phosphonodiethylpropionate. A novel reagent for Stobbe-like condensations

, p. 2119 - 2125 (2007/10/02)
tert-Butyl-3-carboxyethyl-3-phosphonodiethylpropionate was prepared and reacted with a range of aldehydes to give, after hydrolysis, itaconic half esters.
