Next, we explored the scope of functional group tolerance of alkene substrates using D-maltose derivative (1n) as the coupling partner (Scheme 2B). -Methyl styrene derivatives with various electronics substituents such as amide, methoxy, Scheme 3. Selected examples of excited-state palladium-catalyzed late-stage allylation using natural product/drug analogs a a See SI for experimental details. Isolated yield and ax/eq ratio are indicated below each entry. methyl, cyano, sulfonic ester, chloro, phenyl, trifluoromethyl, dioxolanyl, and thioether groups on different positions of the phenyl ring afforded the corresponding products 4a-4l in 42%-62% yield with up to 14:1 axial/equatorial ratio. Extended conjugations like -methyl vinyl naphthalene were compatible and produced the corresponding products 4m and 4n in 47% and 66% yield, respectively, and with good stereoselectivity. Heteroarenes, such as pyridine and thiophene containing alkenes, were viable substrates, affording the desired products 4o and 4p in 42% and 62% yield, respectively. Trisubstituted alkenes, including β-alkylated -methylstyrenes, reacted well, forming the desired products 4q and 4r in good yield and selectivity. Less reactive, 1,1-dialkyl substituted olefins were also amenable to this catalytic process, delivering the corresponding products 4s and 4t in 51% and 38% yield, respectively.
