The exploration of innovative chemical space is a critical step in the early phases of drug discovery. Bis-spirocyclic frameworks occur in natural products and other biologically relevant metabolites and show attractive features, such as molecular compactness, structural complexity, and three-dimensional character. A concise approach to the synthesis of bis-spirocyclic-based compound libraries starting from readily available commercial reagents and robust chemical transformations has been developed. A number of novel bis-spirocyclic scaffold examples, as implemented in the European Lead Factory project, is presented.
Microwave-assisted synthesis of cycloalkanespirohydantoins and piperidinespirohydantoins as precursors of restricted α-amino acids

Cycloalkanespirohydantoins 3 and piperidinespirohydantoins 4 were synthesized from cycloalkanones 9 and piperidones 10 under microwave-assisted conditions. Results are compared with those obtained under thermal conditions. Cycloalkanespirohydantoins 3 were N-protected with Boc group and hydrolyzed under basic conditions to obtain five, six and seven-membered ring restricted α-amino acids 12 in very good overall yields (76-94%).

A series of Cα,α-disubstituted cyclic derivatives of N-(phosphonomethyl) glycine have been synthesized and characterized. They exhibited moderate clastogenicity, low antiproliferative activity on mice bone marrow cells and well expressed cytotoxicity against human tumor cell lines. The 8- and 12-membered cyclic analogs proved superior to the remaining compounds and were found to trigger apoptotic cell death in DOHH-2 cells. The latter compound caused 50% inhibition of the viability of hemobastose-derived cell lines at concentrations ranging from 20 to 67 μM.
