Metathesis, ring-closing

Combination of lipase-catalyzed transesterification with unsaturated vinyl esters as acyl donors and ring-closing metatheses (RCMs) have also been reported [146-148]. Two groups applied this strategy for the synthesis of goniothalamin from cinnamaldehyde [147,148]. The key steps were a transesterification using vinyl acrylate as acyl donor, followed by an RCM, as depicted in Figure 6.55. [Pg.154]

The use of tethered alcohols 50 for cyclizations in ring-closing metatheses (RCM) or as protection agents has already been briefly mentioned in Section 2.2. [Pg.31]

Scheme 6.9. Tandem Zr-catalyzed kinetic resolution and Ru-catalyzed ring-opening/ring-closing metatheses afford chiral chromenes with high optical purity. Scheme 6.9.

A class of olefin metathesis catalysts that contains phosphite ligands has advantages over current catalysts for some challenging reactions, such as ring-closing metatheses of hindered dienes. Cazin et al. [184] modified an existing ruthenium indenylidene metathesis catalyst with triisopropyl phosphite groups to form cis and trans phosphite complexes. [Pg.306]

Diver, S. T Giessert, A. J. Chem. Rev. 2004,104,1317. The term enyne metathesis originally referred to ring-closing metatheses of l,n-enynes and ene-yne metathesis to intermolecular versions of this process. Enyne metathesis is now often used for both types of reactions, and is used in this way in this text. [Pg.1043]

Two ring-closing metatheses were also featured in the formal synthesis of (+)-epiquinamide (2104) hy Panda and coworkers (Scheme 274). Starting with the Gamer aldehyde (S)-2172, they assembled the first metathesis precursor by performing a diastereoselective addition of vinylmagnesium bromide followed by protection of the resulting alcohol as the benzyl ether 2173. Hydrolysis of the N,0-acetal, protection of the alcohol as the TBS... [Pg.396]
