Organometallic nucleophiles for conjugate addition to diallylfumarates were evaluated. For the purpose of the initial screen, we examined only the 1,4-addition. The two catalysts utilized were the commercially available CuBr·SMe2 and easily synthesized bis(N-tert-butylsalicylideneaminato)copper(II), hereafter referred to as Cu(NtBu·sal)2.

Tetrafunctional allyl ether monomer (4-AE) was prepared from trimethylolpropane diallyl ether (2-AE) and isophorone diisocyanate. The synthesis scheme is shown in . Trimethylolpropane tris-(3-mercaptopropionate) (3-SH) was used as the thiol monomer. The monomers were purchased from Aldrich Chemical and used without further purification. 2,2-Dimethoxy-2-phenylacetophenone (Irgacure 651, Ciba Specialty Chemicals) was used as the photoinitiator.

The addition of diethylzinc (1.0 M in diethyl ether) to diallyl fumarate (entry 1) or diallyl maleate (entry 2) and subsequent rearrangement provides the disubstituted unsymmetrical succinate product in good yield and diastereocontrol. Diprenyl fumarate is also an effective reaction partner (entry 3), with SN2′displacement as a competitive process that slightly decreases the yield. The diastereoselectivity is eroded when a bulkier nucleophile, diisopropylzinc (1.0 M in toluene), is used (entry 4).

The conjugate addition of nonstabilized organometallic nucleophiles to α,β-unsaturated carbonyls is a staple of organic synthesis, but the fumarate and maleate electrophile subclass in this reaction family has received scant attention relative to simple enones and enoates. The comparative lack of research activity is surprising since maleic and fumaric acid derivatives represent cheap progenitors to functionalized succinic acids. Notable advances in this area have been reported. Ibuka and co-workers disclosed organocopper(I)–Lewis acid additions to fumarate esters that afforded good yields of the addition products; however, olefin reduction was a competing reaction pathway. Hayashi and co-workers have reported enantioselective rhodium-catalyzed 1,4-additions of arylboronic acids to fumarates and maleates. While these examples provide useful conjugate adducts, a nonobvious feature of the reported additions is that the carbonyls in the products are still functionally equivalent and therefore challenging to distinguish. In this paper, we describe the conjugate addition of dialkylzinc reagents to diallyl fumarates with subsequent Ireland–Claisen rearrangement to give unsymmetrical succinate products. A defining characteristic of the title reaction is chemodifferentiation of the two carbonyls that can be exploited in further selective manipulations.

In summary, we have developed a tandem conjugate addition/Ireland–Claisen rearrangment of dialkylzinc reagents and allyl fumarates in good to excellent yields giving substituted succinate products. The reaction renders the two carboxyl groups non-equivalent; consequently, the products can be selectively manipulated in subsequent synthetic operations.

The first step involves the platinum catalyzed hydrosilylation of diallyl maleate (DAM) with trichlorosilane. By purifying the DAM and using Karstedt's Pt catalyst, one obtains the bis-trichlorosilyl intermediate in > 98% yield. The utilization of diallyl fumarate in this step does not provide significant advantage over the maleate isomer.
