    • The invention relates to an improved process for the preparation of an advanced synthetic intermediate of ACE inhibitors. In one aspect, the present invention is based on a novel process for the preparation of an aldehyde of formula (I), wherein (N) PrG is a protected amino group, R is an alkyl or aralkyl group and X 1-4 are each independently H or a non-reacting substituent, which comprises hydroformylation of an α-olefin of formula (II), by reaction with syngas (CO/H 2 ) in the presence of, as catalyst, a group VIII transition metal complex of a phosphorus-containing ligand. Aldehyde (I), the product of linear hydroformylation, is formed in preference to aldehyde (III). In another aspect of the invention, α-olefin (II) is a novel composition. The process to convert (II) to (I) enables an efficient manufacturing route to MDL 28,726 and analogues.

    • Phenolic glycol ethers, e.g., ethylene glycol phenyl ether, are prepared by a continuous, nonaqueous process comprising the steps of (A) contacting under isothermal reactive conditions in a first reactor or reaction zone an alkylene oxide, e.g., ethylene oxide, with (i) a stoichiometric molar excess of a phenolic compound, e.g., phenol, and (ii) a catalytic amount of a base, e.g., sodium hydroxide, homogeneously dispersed throughout the phenolic compound, to form a first intermediate phenolic glycol ether product, (Bj transferring the first intermediate phenolic glycol ether product to a second reactor or reaction zone, and ( C) subjecting the first intermediate phenolic glycol ether product to adiabatic reactive conditions in the second reactor or reaction zone to form a second intermediate phenolic glycol ether product comprising phenolic glycol ether, unreacted phenolic compound, catalyst, water and byproduct glycols. In addition, the mono-/di-product weight ratio can be adjusted by increasing or decreasing the amount of base catalyst employed.
