Abstract
The cyclopropanation of dihydrofuran and dihydropyran with methyl 1-(silanyloxy)vinyl diazoacetates in the presence of chiral Rh(II)-catalysts affords cyclopropanes with high diastereo- and enantioselectivitiy. The cyclopropanes, in turn, rearrange to dihydrofurans upon desilylation with TBAF.
