The newderivative 5beta-chloro-4alpha-methoxysantonin oxime waspreparedfrom 5beta-chloro-4alpha-methoxysantonin by reaction with hydroxylamine hydrochloride in the presence of pyridine. The structure was established by IR, UV and PMR spectroscopies.
Studies on the Chlorinated α-Santonins. III. Revised Structure of α-Santonin Chlorohydrin
The molecular structure of α-santoninchlorohydrin is revised to 5β-chloro-4α-hydroxysantonin from 4α-chloro-5α-hydroxysantonin (Hendrickson and Bogard) by X-ray analysis of the corresponding 5β-chloro-4α-methoxysantonin.
