Abstract
The direct photolysis of cyclopentyl-type nitrites allows to detection , by EPR spectroscopy, the corresponding delta-valerolactam-1-oxyl typ e radical, owing to a ring expansion process as reported for steroidal 17-nitrites. For the formation of these radicals a 1,6 exo ring closu re process of the intermediate 5-nitrosopenlanoyl-type radical is invo lved. (C) 1997 Elsevier Science Ltd.
