A variety of α-methoxy amides were prepared either by selectivereduction of the exocyclic carbonyl of a 2-acyl-3,4-dihydroisoquinolone and subsequent trapping of the resultant α-hydroxy amide with acidic methanol or by reacting the sodium salt of 3,4-dihydroisoquinolone with a functionalized α-chloro ether. These intermediates were reacted with 1-tert-butoxy-1-tert-butyldimethylsiloxy ethene in the
