Abstract

Alpha-6-deoxytetracyclines are prepd. from 6-deoxy-6-dimethyl -6- methylenetetracycline or 11a-chloro-6-deoxy-6-demethyl- 6methylenetetracycline in the presence of triphenylphosphine or a catalyst of formula (I). In the formula, Z means capability of generating bimolecular or trimolecular compound; R'1 is phenyl; benzenesulfonyl or hydrogen; R'2, R'3, R'4 are hydrogen. The alpha- 6-deoxytetracyclines are useful as antiotics.
