Resumo

Studies have previously shown that anthracene and naphthalene derivatives serve as compounds for trapping and chemically generating singlet molecular oxygen {[}O-2((1)Delta(g))], respectively. Simple and efficient synthetic routes to anthracene and naphthalene derivatives are needed, for improved capture and release of O-2((1)Delta(g)) in cellular environments. Because of this need, we have synthesized a dihydroxypropyl amide naphthlene endoperoxide as a O-2((1)Delta(g)) donor, as well as five anthracene derivatives as O-2((1)Delta(g)) acceptor. The anthracene derivatives bear dihydroxypropyl amide, ester, and sulfonate ion end groups connected to 9,10-positions by way of unsaturated (vinyl) and saturated (ethyl) bridging groups. Heck reactions were found to yield these six compounds in easy-to-carry out 3-step reactions in yields of 50-76%. Preliminary results point to the potential of the anthracene compounds to serve as O-2((1)Delta(g)) acceptors and would be amenable for future use in biological systems to expand the understanding of O-2((1)Delta(g)) in biochemistry.
