Reaction of dimethylsulphoxonium methylide with quaternized derivatives of phenolic Mannich bases, and in certain cases with the bases themselves, constitutes a useful synthesis of dihydrobenzofurans.On the other hand treatment of those same quaternized derivatives with diazomethane may be a useful alternative procedure for the preparation of coumarans with base-sensitive groups.

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.Safety of Ethyl 2,3-dihydrobenzo[1,4]dioxine-2-carboxylate, you can also check out more blogs about4739-94-0

Selective introduction of methyl branches into the carbon chains of alcohols can be achieved with low loadings of ruthenium precatalyst [RuH(CO)(BH4)(HN(C2H4PPh2)2)] (Ru-MACHO-BH) using methanol both as methylating reagent and as reaction medium. A wide range of structurally divers alcohols was beta-methylated with excellent selectivity (>99 %) in fair to high yields (up to 94 %) under standard conditions, and turnover numbers up to 18,000 could be established. The overall reaction rate of the complex catalytic network appears to be governed by interconnection of the individual subcycles through availability of the reactive intermediates. The synthetic procedure opens pathways to important structural motifs following the Green Chemistry principles.

A simple method has been developed for the cross dehydrogenative coupling between two different primary alcohols using readily available RuCl2(PPh3)3 as a precatalyst through the borrowing-hydrogen approach. The present methodology is applicable to a large variety of alcohol derivatives including long chain aliphatic alcohols and heteroaryl alcohols. In addition, the methodology was applied in a straightforward protocol to synthesize commercially available fragrances such as Rosaphen and Cyclamenaldehyde in good yields.

Microbial asymmetric reduction of ketone is an efficient tool for the synthesis of chiral alcohols. Many reports are available for the bio-reduction of acetophenone and its derivatives, since it is widely used model substrate. This research focus on exploring the soil fungal isolates for their ability towards the reduction of acetophenone and its derivatives to their corresponding chiral alcohols using growing cells instead of resting cells. Bio-reduction of acetophenone, 4-fluoro acetophenone, and 4-chloro acetophenone were carried out using different fungal cultures isolated from soil. All the isolates exhibited a good reduction capability when grown in an optimal condition. Among the screened fungal cultures, Penicillium sp. and Aspergillus sp. showed significant bioconversion with varying enantio-selectivity. However, the Penicillium sp. has showed maximum ability of bio-reduction. The best performing isolate was characterized using internal transcribed spacer (ITS) region and found to be Penicillium rubens VIT SS1, which showed higher conversion and selectivity more than 90% towards acetophenone and its derivatives. The reaction conditions such as pH, temperature and media were evaluated for the bio-reduction of acetophenone using Penicillium rubens VIT SS1. The substrate loading was increased from 0.5g/L to 6g/L at shake flask level using the optimized condition pH 5±0.5 and temperature 25±2C. This study revealed huge potential of fungal cultures for the synthesis of many aromatic chiral alcohols in a simpler, novel and cost effective manner.

3-Hydroxypyrimidine-2,4-dione (HPD) represents a versatile chemical core in the design of inhibitors of human immunodeficiency virus (HIV) reverse transcriptase (RT)-associated RNase H and integrase strand transfer (INST). We report herein the design, synthesis and biological evaluation of an HPD subtype (4) featuring a cyclohexylmethyl group at the C-6 position. Antiviral testing showed that most analogues of 4 inhibited HIV-1 in the low nanomolar to submicromolar range, without cytotoxicity at concentrations up to 100 muM. Biochemically, these analogues dually inhibited both the polymerase (pol) and the RNase H functions of RT, but not INST. Co-crystal structure of 4a with RT revealed a nonnucleoside RT inhibitor (NNRTI) binding mode. Interestingly, chemotype 11, the synthetic precursor of 4 lacking the 3-OH group, did not inhibit RNase H while potently inhibiting pol. By virtue of the potent antiviral activity and biochemical RNase H inhibition, HPD subtype 4 could provide a viable platform for eventually achieving potent and selective RNase H inhibition through further medicinal chemistry.
