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.
