A decagram-scale synthesis of seven new building blocks of 1-oxaspiro[3.3]heptane family is described. This general approach requires 6 to 13 operationally simple steps starting from commercially available and inexpensive 3-oxocyclobutane-1-carboxylic acid. Expedient synthetic routes enable the straightforward access to these novel modules. Finally, the generation of virtual combinatorial library using
