cyclizations of E,E-dibenzylidenesuccinate esters have been developed as an efficient synthetic route to 1-aryl-1,2-dihydronaphthalenes. This reaction has been used in the synthesis of the naturally occurring lignans (+/-)-cagayanin and (+/-)-galbulin.
E,E-二亚苄基琥珀酸酯的酸催化环化已被开发为合成1-芳基-1,2-二氢萘的有效途径。该反应已用于合成天然木脂素(+/-)-花青素和(+/-)-球蛋白。
