Patent ID: 8912347

Claim:
A method of synthesizing a compound represented by Formula I, comprising: reacting a compound represented by Formula II with a compound represented by Formula III, wherein: Y is —O(hydrocarbyl); M is SnR 16 R 17 R 18 wherein R 16 , R 17 , and R 18 are each hydrocarbyl; W is —O; W b is —OH or —OSiR 30 R 31 R 32 , wherein R 30 , R 31 , and R 32 are each hydrocarbyl; Z is O; R 1 is H; R 2 , R 3 , and R 6 are each independently selected from hydrogen and hydrocarbyl; R 4 is CH 3 or CO 2 CH 3 ; R 5 is selected from hydrogen, hydrocarbyl, substituted hydrocarbyl, heteroatom-containing hydrocarbyl, or substituted heteroatom-containing hydrocarbyl; and R 7 and R 8 are each independently selected from hydrogen, hydrocarbyl, substituted hydrocarbyl, heteroatom-containing hydrocarbyl, or substituted heteroatom-containing hydrocarbyl, wherein two or more adjacent R groups optionally combine to form a ring; under conditions sufficient to cause bond formation between a compound of Formula (II) and a compound of Formula (III) to create a coupling adduct; and contacting the coupling adduct with a proton source to form a compound of Formula (I).
