A process is provided for the selective oligomerisation of C5 to C20 alpha-olefins to produce polyalphaolefin oligomers with a molecular weight distribution that is suitable for use in lubricant base oils.

Described herein are methods of oxidative coupling of aryl boron reagents with sp.sup.3-carbon nucleophiles, and ambient decarboxylative arylation of malonate half-esters via oxidative catalysis.

A sacubitril intermediate, a preparation method therefor, and use thereof. A key intermediate N-Boc amino alcohol represented by formula (10) or formula (10-a) can be efficiently prepared. The intermediate can be used to prepare a neutral endopeptidase (NEP) inhibitor or a prodrug thereof, particularly a NEP inhibitor comprising a skeleton of -amino--biphenyl--methylalkanoic acid or ester, such as sacubitril. Also provided are intermediates for preparing formula (10) or formula (10-a). Raw materials of the process route are cheap, the operation is simple and convenient, the production cost is low, and the method is suitable for industrial production
