simple and efficient method for the preparation of 5-bromoisatins
Authors
abstract
isatin, n-methyl isatin and n-benzylisatin were smoothly monobrominated in the 5-position by treatment with pyridinium bromochromate (pbc) in acetic acid medium. in the similar conditions indigo underwent bromination and oxidation to give 5-bromoisatin in high yield.

A simple and efficient method for the preparation of 5-hydroxy-3-acyltetramic acids
Oxidation of the bisenolates of 3-acyltetramic acid to the corresponding 5-hydroxylated compounds using molecular oxygen is reported. The deprotection of the resulting compounds was also achieved.
full textA Simple, Artistic and Efficient Modification of the Inversion Method
The simplest and fastest way of producing an acceptable and accurate cast is by adopting the two-pour or inversion method. This process is slightly cumbersome and messy due to difficulty of access. A much more efficient, easy and artistic way of accomplishing it is described by adopting a Rotating Cake Icing Table with a Silicone Baking Mat on top as an autoclavable non-stick barrier.
full textSimple and Economical Method for the Preparation of MgO Nanostructures with Suitable Surface Area
A facile and simple method was proposed to control the size and shape of the MgO nano structures with high surface area in the presence of efficient and cheap templates like PEG 200, PEG 600, PEG 4000 and sorbitol at low temperature within a little time. Nano rods and Nanoparticles have been achieved by applying these templates and altering other growth parameters. The products were charact...
