Abstract

A stereoselective synthesis of the decahydrofluorene core of the hirsutellones was accomplished in eight steps and in 43% overall yield. The key step of the synthesis is the highly stereoselective intramolecular Diels–Alder cyclization of the siloxacyclopentene-constrained tetraene 1.

    However, there have been few medicinal chemistry studies39 on this compound family probably because of their reputation as generally toxic. As far as we know, the total syntheses of 15 cytochalasins have been reported so far (Table 1),43–54 with the last being one of ours.54 Our interest in cytochalasins was the result of their chemical diversity, often associated with structural complexity, and of their natural function for the fungal producers and therefore of their biological potential.

    An additional three steps were required to convert advanced intermediate 339 to the natural product. The synthesis of (±)-rocaglamide by Frontier72 utilizes a Nazarov cyclization of a benzofuran and a stannyl alkoxyallene to form a cyclopentenone (Scheme 42). The synthesis begins with addition of vinylmagnesium bromide to the known benzofuranone 340, dehydration and subsequent oxidative cleavage gave aldehyde 341.

    We thus developed an alternative synthetic route leading to compound 2 through another cascade precursor 4, which was derived from the phenol 6 and the triene 5 via Tsuji–Trost reaction. The triene 5 was tracked back to the Wittig reagent 9,13 aldehyde 7,14 and ethyl glyoxalate (route 2 in Fig. 2). The known aldehyde 7, derived from isopulegone in two steps, was reduced with NaBH4 and then protected as a TBS ether to afford 21 in 79% yield over two steps (Scheme 3).
