Mass Spectral

The mass spectra of bromonitroacetophenones, intermediates in the synthesis of phenethanolamine derivatives containing a nitro and bromo group in the aryl ring, have been studied. The acetophenones were converted into the corresponding α,β-epoxystyrenes, which were then treated with various amines, and proton magnetic resonance and mass spectral studies were used to confirm the direction of ring opening and purity of the products.

Phenylhydrazone Derivatives

Ultraviolet irradiation of 3β-nitrito-5α-lanostane was found to follow an unusual reaction pathway and yield 2-oximo-3-oxo-3,4-seco-5α-lanostane (IV). The new aldehyde was easily converted to oxime and phenylhydrazone derivatives. Acetylating the photolysis product led to an oxime acetate (IX) which readily rearranged to 1-cyano-3,4-seco-5α-lanostane (III). Confirmation for the structural assignments was obtained from a series of proton magnetic resonance and mass spectral studies. Application of the new photochemical reaction was suggested to preparation of certain aldehydes otherwise accessible only with difficulty.
