Pyrolysis of bisergostatrienol gives, in addition to neoergosterol, 19-norergosta-3,5,7,9,22-pentaene, 1,10-secoergosta-3,5,7,9,22-pentaene, 1,10-secoergosta-5,7,9,22-tetraen-3-ol, and ergosta-5,8(14),22-trien-3β-ol. The structure of the 1,10-seco-sterol was established by degradation of the side chain, by dehydration to a styrene (the 1,10-seco-pentaene), and by n.m.r. and mass spectrometry.
