SUBSTITUTED PHENOXY-AMINOPROPANOLS

Substituted phenoxy-aminopropanols of the formula STR1 wherein R is a branched-chain alkyl of 3 or 4 carbon atoms, R 1 is hydrogen, halogen or lower alkyl and R 2 and R 3, independently, are hydrogen, halogen, lower alkyl, lower alkoxy or lower alkylthio, and pharmaceutically acceptable acid addition salts thereof, are described. A process for their preparation, as well as pharmaceutical preparations containing them are also described. The compounds of formula I and their salts possess cardioselective beta-adrenergic blocking activity and antihypertensive activity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: benzodioxans, you can also check out more blogs about214894-89-0

Kinetics and Mechanism of the Arase-Hoshi R2BH-Catalyzed Alkyne Hydroboration: Alkenylboronate Generation via B-H/C-B Metathesis

The mechanism of R2BH-catalyzed hydroboration of alkynes by 1,3,2-dioxaborolanes has been investigated by in situ 19F NMR spectroscopy, kinetic simulation, isotope entrainment, single-turnover labeling (10B/2H), and density functional theory (DFT) calculations. For the Cy2BH-catalyzed hydroboration 4-fluorophenylacetylene by pinacolborane, the resting state is the anti-Markovnikov addition product ArCH = CHBCy2. Irreversible and turnover-rate limiting reaction with pinacolborane (k ? 7 ¡Á 10-3 M-1 s-1) regenerates Cy2BH and releases E-Ar-CH?CHBpin. Two irreversible events proceed in concert with turnover. The first is a Markovnikov hydroboration leading to regioisomeric Ar-C(Bpin)?CH2. This is unreactive to pinacolborane at ambient temperature, resulting in catalyst inhibition every ?102 turnovers. The second is hydroboration of the alkenylboronate to give ArCH2CH(BCy2)Bpin, again leading to catalyst inhibition. 9-BBN behaves analogously to Cy2BH, but with higher anti-Markovnikov selectivity, a lower barrier to secondary hydroboration, and overall lower efficiency. The key process for turnover is B-H/C-B metathesis, proceeding by stereospecific transfer of the E-alkenyl group within a transient, mu-B-H-B bridged, 2-electron-3-center bonded B-C-B intermediate.

Iron-Catalyzed Borrowing Hydrogen beta- C(sp3)-Methylation of Alcohols

Herein we report the iron-catalyzed beta-C(sp3)-methylation of primary alcohols using methanol as a C1 building block. This borrowing hydrogen approach employs a well-defined bench-stable (cyclopentadienone)iron(0) carbonyl complex as precatalyst (5 mol %) and enables a diverse selection of substituted 2-arylethanols to undergo beta-C(sp3)-methylation in good isolated yields (24 examples, 65% average yield).

Direct C-OH/P(O)-H dehydration coupling forming phosphine oxides

A t-BuONa-mediated C-OH/P(O)-H cross dehydration coupling to produce alkylphosphine oxides is developed. This reaction employed readily available alcohols and P(O)-H compounds as the starting materials, providing an efficient alternative method for constructing sp3 C-P bonds. A reasonable reaction path involving dehydration and subsequent regio-selective hydrophosphorylation of the resulting alkenes was proposed.
