Whilst this work is related to, and appears to be contemporaneous with, that of Acton (ref. 4), and of Haynes and Vonwiller (ref. 5), Jung seems not to have appreciated the nature of the oxygenation- cyclization (see Scheme 1 in the Jung paper, cf. Jung's structure 8 for which no data is presented).
