The SnCl4 catalyzed glycosylation reaction of peracetylated b-D-galactopyranose derivatives with terminally unsaturated C3–C11 alkenols was used for the synthesis of some C3–C11 alkenyl b-D-galactopyranosides, as precursors for unsaturated neutra

Tetradecanoic acid was decarboxylated by means of lead(IV) acetate (LTA) under thermal (81 °C) and photolytic (r.t.) conditions in benzene solution. The mixture of products, obtained in thermal reaction, consists of esters (acetoxyalkanes and carbox

Publikováno v: Tetrahedron. 58:9001-9006

Acylation of ferrocene by an acylating agent generated in situ from the corresponding carboxylic acid and phosphorus trichloride, in the presence of the catalyst generated electrochemically from a sacrificial aluminum anode, was investigated. The cor

Acetophenone, 2,2-dimethylcyclopentanone, 3,3-dimethyl-2-butanone, 3-methyl-2-butanone, and 2-pentanone were reduced with borane mediated by (S)-alanine, (S)-methionine, (S)-leucine, (S)-valine, and (S)-isoleucine in very good yields giving predomina

Fully-Naphthalenoid Hydrocarbons and their Conjugation Modes

Autor: Ivan Gutman, Vesna Petrović, Aleksandar V. Teodorovic, Sven J. Cyvin

Publikováno v: Polycyclic Aromatic Compounds. 4:183-189

A fully-naphthalenoid hydrocarbon (FUN) is a benzenoid hydrocarbon whose all π-electrons can be (formally) grouped into disjoint naphthalene-units. The cyclic conjugation in FUNs is studied by means of the energy-effects of their various cycles. It

Publikováno v: Tetrahedron. 49:1725-1738

(−)-B-Chlorodiisopinocampheylborane [(−)-DIP-ChlorideTM, 1], introduced by us several years ago, has been shown to reduce prochiral aryl and alkyl perfluorinated ketones to the corresponding optically active alcohols in very high ee. For example,
