Tin tetrachloride, as Lewis acid

When the synthesis of homoberbine 250 from amide 249 (see Section 2.6.1.2) proceeds with tin tetrachloride as Lewis acid at 60°C, a complex... [Pg.143]

A similar cycli/aiion with tin tetrachloride as Lewis acid and quantitative yields is given in M. E Kuehne, W. G Bommann. W H Parsons, T.D. Spit/er. J.F Blount J Zubicta. J Org Chem. 1988, 53. 3439. [Pg.160]

An excess of BCl3 is necessary in these polymerizations because BCljOAc is a Lewis acid too weak to complete polymerization within a reasonable time. A variation of this approach employs alkyl bromides as initiators and tin tetrachloride as Lewis acid [273]. [Pg.354]
