CYCLO-ADDITION REACTIONS OF THIOFLUORENONE WITH NITRONES

Thiofluorenone reacts with C-phenyl-N-methylnitrone to give, initially, a 1,2,5-oxathiazolidine.Spontaneous loss of sulphur monoxide then produces a dipolar species which reacts with a second molecule of thiofluorenone to give a 1,2-thiazolidine.This thiazolidine partially isomerizes to a 1,3-thiazolidine on heating.The corresponding 1,2-thiazolidine 1-oxide similarly undergoes a cycloreversion-recyclization reaction to the isomeric 1,3-thiazolidine 1-oxide.The reaction of thiofluorenone with C-phenyl-N-phenylnitrone gives a 1,2-thiazetidine 1-oxide, a benzothiazine S-oxide, and a thiazolidine.The formation of the first two products can be explained by involving a rearrangement of the primary 1:1 adduct; the last product may derive from the same adduct by loss of sulphur monoxide followed by a reaction with a second molecule of thione.
