Oxovanadium complexes work as useful catalysts for the oxidation of propargylic alcohols to the corresponding carbonyl compounds in the presence of 3 ? molecular sieves under an atmospheric pressure of molecular oxygen.

Iodoarene catalysis is a powerful methodology that usually requires an excess of oxidant, or of redox mediator if the terminal oxidant is dioxygen, to generate the key hypervalent iodine intermediate to proceed efficiently. We report that, using the spiro-cyclization of amides as a benchmark reaction, aerobic iodoarene catalysis can be enabled by relying on a pyrylium photocatalyst under blue light irradiation. This unprecedented dual organocatalytic system allows the use of low catalytic loading of both catalysts under very mild operating conditions.
Ethyl lactate as a renewable carbonyl source for the synthesis of diynones
Solas, Marta,Suárez-Pantiga, Samuel,Sanz, Roberto

Ethyl lactate, a sustainable feedstock, serves as a highly attractive building block for the synthesis of value-added chemicals such as skipped diynones and, after gold-catalyzed transposition, conjugated diynones. Green solvents are involved in all steps
