Successive Promotion of Formal [3+2] Cycloaddition of Aryl Methyl Ketones by I<sub>2</sub> and Zn: Access to 2-Hydroxy-4-morpholin-2,5-diarylfuran-3(2<i>H</i>)-ones with a Quaternary Carbon Center
2-Hydroxy-4-morpholin-2,5-diarylfuran-3(2H)-one derivatives were constructed sequentially using iodine and zinc dust from simple and readily available methyl ketone and morpholine as the starting materials. Under mild conditions, C–C, C–N, and C–O bonds formed in a one-potsynthesis. A quaternary carbon center was successfully constructed, and the active drug fragment morpholine was introduced into the molecule

This invention relates to a method for increasing the growth rate of warm-blooded animals by orally or parenterally administering thereto a growth enhancing amount of a m-cyanophenethanolamine compound. It also relates to a method for reducing the body fat of warm-blooded animals and/or inhibiting the deposition of fat in warm-blooded animals by orally or parenterally administering thereto an effective amount of a m-cyanophenethanolamine compound.

The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
