The synthesis of 1H-2-naphtho[2,3-c]thiapyran-5,10-dione-2,2-dioxide (2), a 2-sulfone derivative of the natural pyranonaphthoquinone pentalongin (1), was accomplished using the acid-catalysed cyclisation of the naphthoquinone sulfone acetal 6 as a key step in the synthesis.
1 H -2-萘并[2,3- c ] thiapyran-5,10-dione-2,2-dioxide(2)的合成是使用天然吡喃并萘醌五肽酮(1)的2-砜衍生物完成的。萘醌砜缩醛6的酸催化环化反应是合成中的关键步骤。
