The construction of d3-methylated all-carbon quaternary stereocenters has been successfully developed via carbene-catalyzed desymmetrization of prochiral d3-methylated oxindolyl 1,3-diketones. Three new stereogenic centers were efficiently constructed with satisfactory outcomes. Diverse spiro-polycyclic molecules with a d3-methylated all-carbon quaternary stereocenter were generated in good to excellent yields with good to excellent diastereoselectivities and excellent enantioselectivities. This reaction features a broad substrate scope, good functional-group tolerance, and easy scale-up.

An enantioselective synthesis of isolated acyclic quaternary stereocenters was achieved using metal-catalyzed Gosteli-Claisen rearrangements of allyl vinyl ethers. A concise synthesis of 2-t-butoxycarbonyl allyl vinyl ethers by regioselective Petasis methylenation and stereoselective Suzuki-Miyaura cross-coupling reactions of iodoallyl t-butyl oxalates was developed. Ethers with a terminally unsubstituted vinyl group and a terminally disubstituted allyl portion are readily accessible by this method. In addition to the metal-catalyzed Gosteli-Claisen rearrangements, organocatalytic variant of the Gosteli-Claisen rearrangement was investigated. A modular synthesis of several new, chiral cyclic phosphoramide-based, thioureas, formamidines and thiosemicarbazides was developed and these phosphoramides were examined for their ability to catalyze the Gosteli-Claisen rearrangement of a selected allyl vinyl ether. A variety of E-3-(arylidene)-5-(alkyl/aryl)-2(3H)-furanones were synthesized by employing regioselctive addition of -aryl acrylic acids with iodoacetylenes and subsequent intramolecular Heck reaction of Z-acyloxy iodo alkenes. The approach was applied in a formal synthesis of the naturally occurring kinase inhibitor BE-23372M.
