The synthesis of insect pheromones published in the period 2005-2007 is reviewed. A total of 66 compounds from different insect orders and belonging to different structural classes were included.

Commercially available iodine has played an important role in organic synthesis. The review describes the use of iodine in the synthesis of several iodolactones and lactones. The cyclization of nonconjugated unsaturated acids, diallyl- hydroxyacetic acids, benzyl carbamates, norbornene derivatives, aryl-allenoic acids, olefinic amides and γ-methallyl malonic acids with iodine leads to the formation of iodolactones.

This brief review article describes the progress made in the synthesis of medium- and large-sized carbocyclic and heterocyclic rings by the application of the palladium-catalyzed reactions.

Nanohydroxyapatite microsphere (HAp) as an environmentally benign and biocompatible material is found to be efficient catalyst for the synthesis of α-hydroxy and α-amino phosphonates derived from carbonyl compounds. This heterogeneous catalyst does not require aqueous workup, additionally catalyst can be simply recovered and recycled.

This review focuses on photolytic reactions of diazo compounds, namely aryl-diazo alkanes and α-diazo carbonyl compounds, covering their synthetic applications such as Wolff rearrangement, 1,2-shift, X-H insertion, cyclopropanation, hydrogen abstraction and reaction with oxygen as well as physical organic studies, with special relevance to mechanistic considerations. Singlet-triplet gap studies and the solvent influenc Read More
