useful carbamoyl fluorides. High selectivity for fragmentation over a potentially competing Beckmann rearrangement was observed. This protocol has a distinct mechanism and thus a different substrate scope compared with other synthetic methods. α-Oximinoamides derived from the readily available secondary amines, lactams, or isatins were converted into structurally diverse carbamoyl fluorides.

The present invention is directed to various 3',4'-dihydro-2'H-spiro[indoline-3:1'-isoquinolin]-2-one compounds and methods for treating disease states and/or conditions which are mediated through sphingosine-1-phosphate receptor(s). The present invention is also directed to the use of these compounds as anticancer agents and as modulators of sphingosine-1-phosphate receptor function in the treatment of disease states and/or conditions which are mediated through these receptors. In addition, the invention relates to pharmaceutical compositions comprising one or more of these compounds alone or in combination with other therapeutic agents. The invention is also directed to methods of treatment of cancer and/or conditions that may respond to the modulation of sphingosine-1-phospate receptor function and which employ compounds of the present invention or pharmaceutical compositions comprising one or more of the compounds of this invention.
the spiro[4,5]decane system. Spiro[4,5]decanes bearing oxindoles containingthree stereogenic centers and spirooxindole polycycles having seven stereogenic centers, including two all‐carbon chiral quaternarycenters and one tetrasubstituted chiral carbon center, were obtained with high diastereo‐ and enantioselectivities.
Herein, we disclosed an efficient protocol for the construction of chiral 3-allyl-3-hydroxyoxindoles via the enantioselectiveallylation reaction of isatins and allylboronates catalyzed by a simple binary acid Bi(OAc)3/CPA system under mild conditions. The synthetic utility of this strategy has been demonstrated through the formal synthesis of ent-CPC-1.
