Site-selective catalytic deaminative alkylation of unactivated olefins

A catalytic deaminative alkylation of unactivated olefins is described. The protocol is characterized by its mild conditions, wide scope - including the use of ethylene as substrate -, and exquisite site-selectivity pattern for both a-olefins and internal olefins, thus unlocking a new catalytic platform to forge sp3-sp3 linkages, even in the context of late-stage functionalization.

Benign catalysis with iron: Unique selectivity in catalytic isomerization reactions of olefins

The use of noble metal catalysts in homogeneous catalysis has been well established. Due to their price and limited availability, there is growing interest in the substitution of such precious metal complexes with readily available and bio-relevant catalysts. In particular, iron is a "rising star" in catalysis. Herein, we present a general and selective iron-catalyzed monoisomerization of olefins, which allows for the selective generation of 2-olefins. Typically, common metal complexes give mixtures of various internal olefins. Both bulk-scale terminal olefins and functionalized terminal olefins give the corresponding products under mild conditions in good to excellent yields. The proposed reaction mechanism was elucidated by in situ NMR studies and supported by DFT calculations and extended X-ray absorption fine structure (EXAFS) measurements.

Diastereoselective cycloisomerizations of enediynes via palladium catalysis

Considerations of atom economy drive a search for reactions that are simple additions which, performed intramolecularly, are cycloisomerizations. Exposure of acyclic enediynes to a catalyst generated by mixing a Pd(0) complex with acetic acid normally in

Compounds of the formula STR1 wherein one of the radicals R1, R2 or R3 denotes a straight-chain alkyl group having 4 to 8 C atoms and two vicinal hydroxyl groups in the ω,ω-1 or ω-1,ω-2 positions and the two other radicals represent straight-chain or branched alkyl groups having up to 12 C atoms in the position of R1 and R3 and up to 4 C atoms in the position of R2, the total of C atoms in these two alkyl substituents being a maximum of 14, are prepared by oxidation of the corresponding alkenylxanthines and by alkylation with compounds which introduce the dihydroxyalkyl radical or a precursor thereof. The dihydroxyalkyldialkylxanthines are suitable for the treatment of obstructive respiratory tract diseases.

Photochemistry of N-Alk-4-enyl and N-Alk-5-enyl-phthalimides: Two Different Types of Cyclization Reaction

Photochemical reactions of N-alk-4- and -5-enylphthalimides (1a-e) have been investigated.In the photolyses of acetonitrile solutions of (1a-e), intramolecular cyclization reactions accompanying C(=O)-N bond cleavage to give (2a-e) were generally predominant, together with intramolecular hydrogen abstraction in some cases.Photolyses of cis- and trans-N-hex-4-enylphthalimides in acetonitrile solution showed stereospecific cyclization reactions; irridiation of cis-(1e) gave cis-(2e) and that of trans-(1e) gave trans-(2e) selectively with low conversion.In methanol (1d), which has a vinyl ether moiety, gave different types of cyclization product: namely, (8a) and (9a), methanol-incorporated products probably resulting from an intramolecular electron transfer process.
