Switchable Site-Selective Catalytic Carboxylation of Allylic Alcohols with CO2
van Gemmeren, Manuel,B?rjesson, Marino,Tortajada, Andreu,Sun, Shang-Zheng,Okura, Keisho,Martin, Ruben
supporting information, p. 6558 - 6562 (2017/05/29)
A switchable site-selective catalytic carboxylation of allylic alcohols has been developed in which CO2 is used with dual roles, both facilitating C?OH cleavage and as a C1 source. This protocol is characterized by its mild reaction conditions, absence of stoichiometric amounts of organometallic reagents, broad scope, and exquisite regiodivergency which can be modulated by the type of ligand employed.

A novel Ni-catalyzed regiodivergent reductive carboxylation of allyl esters with CO2 has been developed. This mild, user-friendly, and operationally simple method is characterized by an exquisite selectivity profile that is dictated by the ligand backbone.

(Equation presented) In the presence of catalytic amount of NIBr 2 as catalyst precursor, organic halides are reductively coupled at 70°C with acrolein diethyl acetal to give (Z)- and (E)-enolethers by allylic deplacement of an alkoxy group. Subsequent hydrolysis affords β-arylated aldehydes.

To mimic the folded side chain conformation of 1233A (1), which is a 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) synthase inhibitor, 1233A analogs with aromatic rings in the side chain were synthesized. The 2-oxetanone moiety was kept intact. Among 1233A and its synthetic analogs, trans-3-hydroxymethyl-4-[2-(7-methoxycarbonyl-1-naphthyl)ethyl]-2-oxe tanone (23) showed the highest HMG-CoA synthase inhibitory activity in vitro. The structure-activity relationship at the side chain is discussed.
Preparation of Functionalized trans-Perhydroindans from Substituted Benzoic Acids: Reductive Alkylation-Halolactonization-Free Radical Cyclization
