Double bonds microwave-assisted

The synthesis of statistical copolymers consisting of EtOx and 2- soyalkyr -2-oxazoline (SoyOx) via a microwave assisted CROP procedure was reported by Schubert et al. [89]. The SoyOx monomer is based on soybean fatty acids and has an average of 1.5 double bonds per monomer unit. The designed polymer... 

Curiously, the N-benzyl moiety on a variety of /3-lactams was untouched by the microwave-assisted CTH reactions. The authors further elaborated this interesting strategy for the reduction of the double bond in an unsaturated sugar moiety, without inducing the ring fission of the attached /1-lactam side chains (Scheme 46). 

In studies on carbapenem synthons, a series of monocyclic j3-lactams of type 27 and 29 were generated with an exo-alkene group at C-3 [38]. The conjugated double bonds herein could be reduced easily under microwave-assisted CTH conditions with stereospecificity leading to only cis jS-lactams of type 28 and 30, which is highly desirable (see Scheme 18).
