Substoichiometric loadings of DBU catalyse the efficient 1,4-addition of alcohols and non-nucleophilic amines such as pyrrole to activated alkenes; the application of this methodology in a one-pot synthesis of a natural product, and as a novel strategy for the synthesis of mono-protected 1,3-carbonyl compounds is reported.
The present invention concerns novel compounds of the formula: ##EQU1## wherein R.sub.1 to R.sub.9 have various significances including e.g. alkyl, X and Y include O and S and s, v, w and z are O or whole numbers and Ar.sub.1 is a formyl phenyl radical. The compounds possess insecticidal properties.
