The preparation of several functionalized furan derivatives and attempts to transform them into a derivative containing 6 H -furo[3,4-b]furanone skeleton towards the construction of naphtho[2,3- b ] furan are described. Attempted Pummerer reaction of a furan sulfoxide derivative produced four interesting furan derivatives. Base promoted annulation between methyl 2-(phenylsulfinylmethyl)-3-furoate and 2-cyclohexenone proceeded to give dihydro naphtho[2,3- b ]furanone derivative in a regiospecific manner.
