Diels Alder Reaction

Homochiral AB segments for (+)- and (–)-pillaromycinone were prepared in 11 steps from 2-acetylfuran. The synthesis featured an intramolecular Diels–Alder reaction of a 2,5-disubstituted furan and a hydroxyl-directed homogeneous hydrogenation of the tetrasubstituted alkene double bond of two enones. The CD segment was attached by a modified Staunton–Weinreb annulation to produce the desired homochiral tetracycle 21c related to (+)-pillaromycinone. An unusual acetonide migration enabled the synthesis of a tetracyclic model for premithramycinone.

Diels Alder Reaction

Aimed at predicting relative reactivities, density functional theory (DFT) calculations were carried out on a series of Diels–Alder reactions involving silylvinyl derivatives reacting with cyclopentadiene as part of a synthetic research project. Using three reactions for which experimental rate data are available to calibrate our calculations, we computationally pinpointed the best synthetic route to bicyclo[2.2.1]hept-5-ene-2,2-diylbis(trimethylsilane) (1). The synthesis begins with the Diels–Alder reaction of cyclopentadiene (2) with commercially available (1-bromovinyl)trimethylsilane (6).
