Cycloaddition reactions between a new homochiral imidazolone-derived nitrone afford cycloadducts in high yield and with high stereoselectivity. Subsequent cycloadduct elaboration affords the gamma-lactones of gamma-hydroxy-alpha-amino acids as well as the optically pure amino acids themselves.

Biomolecular temperature sensors can be used for efficient control of large-volume bioreactors, for spatiotemporal imaging and control of gene expression, and to engineer robustness to temperature in biomolecular circuit design. Although RNA-based sensors, called "thermometers", have been investigated in both
