Dynamic diastereoselectivity during iron carbonyl mediated spirocyclization reactions

Dynamic diastereoselectivity during Fe(CO)3 promoted [6 + 2] ene spirocyclization of 35a and 35b, having a chiral center on the pendent side chain, was investigated and gave rise to products 28a and 28b instead of four possible isomers. From th
