Features of the Wittig olefination reaction of menthone lactol and its aluminate by several n-alkylidenetriphenylphosphoranes were studied. The product of the reaction with ethylidenetriphenylphosphorane was used in the synthesis of the sexpheromone of peach leaf miner Lyonetia clerckella.

Abstract We earlier discovered a newreaction in the chemistry of organoaluminum compounds (OACs), specifically, the formation of O-isobutyl acetals on low-temperature (–70°C) treatment of seven-membered lactones with a double (or more) molar amount of diisobutylaluminum hydride (DIBAH) in methylene chloride. To assess the boundaries for the formation of isobutyl acetals depending on the ring size

Three new approaches to the synthesis of 1-bromo-3S-methylundecane, a key synthon in the synthesis of (S,S,S)-diprionylacetate, a sexpheromone of pinesawflies of the genera Diprion and Neodiprion, were proposed based on chemo-and stereoselective transformations of L-(-)-menthol derivatives.

Potentially useful 15- and 20-membered macrolides containing azine or hydrazide groups were synthesized from L-menthol via [1+1]-condensation at room temperature of 3R,7-dimethyl-6-oxooctyl-3R,7-dimethyl-6-oxooctanoate, which was obtained from 3R,7-dimethyl-6-oxooctanal via a Tishchenko reaction, with hydrazine hydrate or malonic acid dihydrazide.

Iodide-bound ruthenium–JOSIPHOS complexes catalyze the redox-neutral C–Ccoupling of primary alcohols 2a–2r with the gaseous allene (propadiene) 1a to form enantiomerically enriched homoallylic alcohols 3a–3r with complete atom efficiency. Using formic acid as the reductant, aldehydes dehydro-2a and dehydro-2c participate in reductive C–Ccoupling with allene to deliver adducts 3a and 3c with comparable
