the [2,3]-wittig rearrangement is the transformation of an allylic ether into a homoallylic alcohol via a concerted, pericyclic process. because the reaction is concerted, it exhibits a high degree of stereocontrol, and can be employed early in a synthetic route to establish stereochemistry. the wittig rearrangement re...

rearrangements must be carried out at temperatures below
rearrangements must be carried out at temperatures below −60 °c to avoid competitive -rearrangement. typically, simple treatment of the substrate with n -butyllithium is sufficient to cause rearrangement. reactions involving butyllithium should be carried out under nitrogen or argon with strict exclusion of water.

the use of chiral bases has afforded enantioenriched rearrangement products in a few cases, although this method does not appear to be general. enantioselectivity in these reactions is often low, suggesting that the association between the conjugate acid of the base and the rearranging carbanion is likely weak.

asps can be used in miniature imaging devices. they do not require any focusing elements to achieve sinusoidal incident angle sensitivity, meaning that they can be deployed without a lens to image the near field, or the far field using a fourier-complete planar fourier capture array. they can also be used in conjunctio...

asps are typically composed of two gratings (a diffraction grating and an analyzer grating) above a single photodiode. asps exploit the moire effect and the talbot effect to gain their sinusoidal light sensitivity. according to the moire effect, if light acted as a particle, at certain incident angles the gaps in the d...
