标 题 :Synthesis of cyclic amidines
发明人：LENTZEN GEORG; NEUHAUS THORSTEN
权利人:LENTZEN GEORG; NEUHAUS THORSTEN; BITOP AG
摘要:The invention relates to an innovative method for synthesis of cyclic amidines. The synthesis starts from a β-, γ- or δ-lactone which is twofold brominated. After esterification of the carboxyl function, the bromine atoms are nucleophilically substituted and the corresponding diamino compound is obtained. The ring closure to the cyclic amidine is accomplished subsequently by reaction with orthoester, imidate or thioimidate. Owing to interposing additional steps for recovery of the diamino compound in enantiomerically pure form, the enantiomers of the cyclic amidines can be stereoselectively synthesized.

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.
