Apio north-methanocarbocyclic nucleosides 1–3 with bicyclo[3.1.0]hexane template were first synthesized. Introduction of hydroxymethyl substituent was efficiently and stereoselectively accomplished by aldol and retro-aldol reaction and fixed conformation was achieved from a modified Simmons-Smith cyclopropanation on a cyclopentane ring.
