Addition of isobutyraldehyde to 1,2-bis(2-hydroxyphenyl)-1,2-diaminoethane (mother diamine) cleanly gives a stable, fused imidazolidine-dihydro-1,3-oxazine ring complex. However, vigorous heating of the fused ring complex gives the diaza-Cope rearrangement product with excellent yield and stereoselectivity. A variety of alkyl aldehydes have been

Global climate change has stimulated efforts to reduce CO(2) emissions. One approach to addressing this problem is to recycle CO(2) directly into fuels or chemicals using photosynthesis. Here we genetically engineered Synechococcus elongatus PCC7942 to produce isobutyraldehyde and isobutanol directly

After vacuum distillation and liquid-liquid extraction, the volatile fractions of dark chocolates were analyzed by gas chromatography-olfactometry and gas chromatography-mass spectrometry. Aroma extract dilution analysis revealed the presence of 33 potent odorants in the neutral/basic fraction. Three of these had
