Synthesis and stereochemistry of 2,2,3-trimethyl-5-aryl-4-aroyloxazolidines

cis-2,2,3-Trimethyl-5-aryl-4-aroyloxazolidines were obtained by heating complex boron trifluoride salts of trans-1-methyl-2-aryl-3-aroylaziridines with acetone. The reaction of complex boron trifluoride salts of cis-1-methyl-2-aryl-3-aroyl-aziridines leads to substituted benzaldehydes and -N-methylaminoacetophenones.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 38–42, January, 1981.
