The 'Silyl-Stobbe condensation' - Synthesis of fulgimides

Organooxyalkylation of 2,5-bis(trimethylsiloxy)-1-phenylpyrrole (1) with aromatic aldehydes 2 and acetone (5) is achieved to yield 2,3-bis[aryl(trimethylsiloxy)methyl]-N-phenylsuccinimides 4 and 2-[aryl(trimethylsiloxy)methyl]-3-[1-methyl-2-(trimethylsilo

Reactions of Trialkylsilyl Trifluoromethanesulfonates, VIII. - Synthesis of O-(Trimethylsilyl)ketene O,N-Acetals, 2,5-Bis(trimethylsiloxy)pyrroles, -furans, and -thiophenes

Ketene O,N-acetals 3, 4, 6, 8 are obtained from N,N-diarylcarboxamides and N-acetylheterocycles 5, 7 by silylation with trimethylsilyl triflate (2) in the presence of triethylamine.Analogous reactions of carboxamides 9 and N-acyllactams 11 yield the keten

Two Total Syntheses of Showdomycin and Related Studies

After a series of model reactions, D-ribose (2) was reacted with 3-(triphenylphosphoranylidene)-2,5-pyrrolidinedione (8a) in THF at reflux to produce 3(E)-2(S),3(S),4(R),5-tetrahydroxy-1-pentylidene)-2,5-pyrrolidinedione (35) (75 percent).Subsequent cyclization of 35 using phenylselenyl chloride followed by hydrogen peroxide gave showdomycin (1) (13 percent) and epi-showdomycin (36) (41 percent).Using a similar strategy 2,3-O-isopropylidene-D-ribose (37b) was reacted sequentially with 1-(triphenylmethyl)-3-(triphenylphosphoranylidene)-2,5-pyrrolidinedione (8b), phenylselenyl chloride, hydrogen peroxide, and trifluoroacetic acid to give (1) (3 percent overall).
