Chimeric azalides with simplified western portions
摘要:
A series of chimeric azalides which are homologous to the azalide antibiotics 2 and 4 in their eastern halves but which have functionally simplified western halves have been semisynthesized from erythromycin A. These chimeric azalides include both macrolactones and macrolactams and vary in ring size from 13 to 16 members. The synthesis, which establishes the ring via a macrolactonization or macrolactamization reaction, requires no protecting groups on the eastern half of the molecule, including the sugars.

The hydrogenbond donating ability of 1,8-naphthalenediol was investigated via a series of 1 " role="presentation"> 1 1 ^1} H, 13 " role="presentation"> 13 13 ^13} C, and 31 " role="presentation"> 31 31 ^31} P NMR experiments. Complexation studies using triphenylphosphine oxide and cyclohexanone as hydrogenbond acceptors revealed that 1,8-naphthalenediol is a more effective hydrogenbond donor
通过一系列1“ role =” presentation“> 1 1 ^ 1} H,13” role =“ presentation”> 13 13 ^ 13} C,研究了1,8-萘二醇的氢键给体能力。 31“ role =” present“>”> 31 31 ^ 31} P NMR实验。使用三苯膦氧化物和环己酮作为氢键受体的络合研究表明,与1-萘酚和8-萘酚相比,1,8-萘二醇是更有效的氢键供体随后,在吲哚与反式β-的Friedel-Crafts型加成反应中证明了其作为氢键催化剂的有效性。

Aus den Knollen von Eleutherine bulbosa (Mill.) Urb. wurde ein neuer Pflanzenstoff, das Eleutherol, isoliert. Auf Grund von Abbaureaktionen, deren wichtigste die Alkalispaltung des Naturstoffes in Eleutherolsäure (4-Oxy-5-methoxy-2-naphtoesäure, IV) und Acetaldehyd darstellte, folgt für Eleutherol die Konstitution I. Eleutherol stellt den ersten in der Natur angetroffenen Naphtalidabkömmling dar.
