Ozonolysis of terminal alkenes followed by reacting with a preheated mixture of CH2Br2-Et2NH affords α-substituted acroleins, which can be converted to α-keto acid derivatives in three steps, under very mild reaction conditions.

o-Iodoxybenzoic acid (IBX), a highly versatile hypervalent iodine(V) reagent, was found to efficiently mediate the dehydrogenation of amines in addition to facilitating the oxidative cleavage of dithioacetals and dithioketals. Through the development of relevant IBX-based protocols, a plethora of useful synthetic intermediates, including imines, oximes, ketones, and aromatic N-heterocycles, were found

Carbocyclic methyl and silyl enol ethers (TBDMS is optimum) can be synthesised regiospecifically by ring closing metathesis using the ‘second generation’ Grubbs ruthenium carbene catalyst in combination with molecular sieves.
