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
