Indium-mediated allylation and Reformatsky reaction on glyoxylic oximes under ultrasound irradiation
A novel and more convenient method for the indium-promoted allylation of glyoxylic oximes based on the use of ultrasonic waves is reported. A similar procedure was used to develop the first example reported in the literature of an indium-mediated Reformatsky reaction on oxime ethers.

SYNTHESIS AND ABSOLUTE STEREOCHEMISTRY OF SERRICORNIN
The absolute stereochemistry of serricornin (4,6-dimethyl-7-hydroxy-3-nonanone) was established as 4S, 6S, 7S by synthesizing both (4S, 6S, 7S)-isomer and its antipode.Only the natural enantiomer was bioactive.by
