An efficient route to synthesize 2'-spiro[2-oxocyclopentyl]cyclopropyl nucleoside analogues via KOtBu promoted Michael addition-initiated cyclopropanation reactions of α-thymine acrylates with α-chloro-cycloalkanones has been developed. A wide range of C(2')-spirocyclic modified nucleoside analogues were obtained with excellent diastereoselectivities (>20:1) and good yields (up to 85%).
