标题:Synthesis of anthracyclines
发明人：JOHNSON FRANCIS; KIM KYOUNG S
权利人:RESEARCH CORP
摘要:There is provided a novel method of synthesizing certain heterocyclic quinones. In particular there is provided a novel and regiospecific synthesis of 9-acetyl-6,11-dihydroxy-4-methoxy-7,8,9,10-tetrahydronaphthacene-5,12-quinone (7,9-dideoxydaunomycinone) which is known intermediate in the synthesis of daunomycinone. There is also provided a method of preparing analogs of 7,9-dideoxydaunomycinone which thus provide for the preparation of known and desired analogs of daunomycinone. Daunomycinone is a known compound which is an intermediate in the preparation of the clinically accepted naturally-occurring antitumor antibiotics daunomycin and its derivitive adriamycin.

标题:Process for the synthesis of 2,2-dialkoxy-propanes
发明人：MESSINA GIUSEPPE; MORETTI MARIO D; SANNA GAVINO; SANNA SALVATORE R; SOMA GIOVANNI
权利人:ENICHEM ANIC SPA
摘要:A new method of synthesis of a 2,2-dialkoxy-propane e.g. 2,2-dimethoxy-propane, is described through reaction of a cyclic ketal, e.g. 2,2-dimethyl-(1,3)-dioxolane, with a boric acid alkyl ester, e.g. boric acid trimethyl ester, in the presence of an acidic catalyst. The reaction may be carried out either in liquid or in vapour phase. In the latter case, heating of the thus obtained intermediate mixture to the reflux temperature should follow the catalytic step.
