presence in natural products. Development of the Pd-catalyzed arylation of butenolides with high selectivity for the γ-position allows for a facile construction of quaternary centers. The preparation of a wide variety of γ-aryl butenolides containing a number of functional groups is outlined. An application of this chemistry for a one-pot synthesis of a tricyclic tetrahydroisoquinolinone is demonstrated
Sulfides are directly converted effectively to the corresponding α-acetoxy sulfides by electrolysis in acetic acid.
通过在乙酸中进行电解,可以将硫化物直接有效地直接转化为相应的α-乙酰氧基硫化物。

An unambiguous and highly enantioselective total synthesis of the naturally-occurring 2(5H)-furanone hamabiwalactone B has been achieved. The key step is a Stille coupling of novel stannylfuranone 2 with (E)-iodoalkene 3, The enantiomeric purity of the synthetic natural product was greater than or equal to 99%, as judged by chiral HPLC, (C) 1998 Published by Elsevier Science Ltd.
