Directed regio- and stereoselective hydroformylation of mono- and 1,3-disubstituted allylic alcohols: A catalytic approach to the anti-aldol-retron

Regioselective and diastereoselective hydroformylation of mono- and 1,3-disubstituted allylic alcohol o-DPPB esters is described. The products represent synthetically important anti-aldol retrons.

CHEMICAL CONVERSIONS OF BUTYRALDEHYDES DURING SEPARATION OF THE PRODUCTS OF OXO SYNTHESIS.

Preliminary studies of separation of the products of oxo synthesis in presence of cobalt salts revealed substantial (up to 30%) losses of aldehydes, and lowering of the temperature limit of stability of the catalyst to 170-180 degree . In particular, it was found that cobalt salts catalyze aldol condensation. In order to determine the optimal separation conditions, with minimization of losses of aldehydes and alcohols and conservation of catalyst stability, it was necessary to study the principal factors determining the degree and interrelationships of the chemical conversions accompanying separation. It is shown that aldol condensation and formation of acetals occur during isolation of butyraldehydes by continuous fractionation of the products of oxo synthesis. Aldehyde losses due to chemical conversions decrease with increase of temperature in the reboiler, and may be virtually eliminated, while the selectivity of formation of the products of aldol condensation increases.
