The crude annulation product is treated with 10 % potassium hydroxide in methanol to saponify the ester side product formed from the reaction of the phenolic product with excess vinylketene ( Scheme 6 ) . center

About 40 years later, Curran described fast new reactions involving iodine transfer, bromine transfer and functional group transfer, and encompassing radical addition ( ATRA ), cyclization ( ATRC ) and annulation.

The Yushchenko administration requested for an extraordinary seating of the Rada, the annulation of the election in the Donetsk and Luhansk oblasts where no observers or journalists were allowed after the closing of the electoral districts.

The anti-ulcer drug, Egualen ( KT1-32 ) was synthesized using this ring expansion-annulation strategy with a rhodium catalyst ( Rh 2 ( OCOt-Bu ) 4 ) in ether.

The Robinson annulation, published by Robert Robinson in 1935, is a base-catalyzed reaction that combines a ketone and a methyl vinyl ketone ( commonly abbreviated to MVK ) to form a cyclohexenone fused ring system.

In 2012, bio-archaeologists, forensic anthropologists, and forensic odontologists created the " Cementochronology Research Program " to provide a platform for researchers interested in the age-at-death estimation through Tooth Cementum Annulation.
37.
Nonetheless, studies performed on cementum annulation have shown a strong correlation between the deposits the known age-at-death and allow to estimate adult age-at-death with a better precision than classical dental and osseous methods.
38.
The Carreira group made use of a magnesium iodide promoted annulation reaction in their approach toward spirotryprostatin B . An oxindole bearing a cyclopropane was reacted with an imine in the presence of the magnesium iodide, triggering the ring-expansion reaction.
39.
Samarium ( II ) iodide is a very common reducing and coupling agent in organic synthesis, for example in the desulfonylation reactions; annulation; Holton Taxol total syntheses; strychnine total synthesis; Barbier reaction and other reductions with samarium ( II ) iodide.

Regardless of the fact that in July 1992 the National Assembly of the Republic of Serbia promulgated the Declaration on the Annulation of the Decision on Absolving Bulgaria of Compensation for War Damages, there was no legal title under which the question of war damages inflicted by Bulgaria could be raised.
