“…;c=c: phenylcyclopropenone (96) produced a nitrogen-free hydrolysis product 97, and 96 with diethylamine gave 97 and the expected product 98.92 The action of aqueous ammonia on 96 resulted in 99, the product from ring fission and subsequent oxidation.92 Treatment of 7 with liquid ammonia gave a-phenyl-/3-amino-frans-cinnamaldehyde (100), possibly by the mechanism shown. 101 The reaction of thioamides with diphenylcyclopropenone (7) led to A/-(2-phenylcinnamoyl)thioamides (101), which underwent further ring closure to form 1,3-thiazin-4-ones 102 or 103,153 depending on the availability of enolizable hydrogens.…”
