Amberlyst A 21 as new and efficient surface catalyst for the cleavage of 2-nitrocycloalkanones
Ballini,Petrini,Polzonetti
, p. 355 - 357 (1992)
Ring cleavage of 2-Nitrocycloalkanones with methanol/Amberlyst A 21 gave methyl ω-nitroalkanoates, O2NCH2(CH2)(n)CO2Me where n = 3-6, 8-10,13, in high yield. Subsequent Nef reaction gave the corresponding ω-oxo compounds which were isolated, in the case of methyl 7-oxoheptanoate and methyl 8-oxooctanoate only, or reduced directly with sodium borohydride to give ω-hydroxyalkanoates. A new formal synthesis of exaltolide (15-pentadecanolide) is also reported.
Ozone: A versatile reagent for solid phase synthesis
Sylvain, Catherine,Wagner, Alain,Mioskowski, Charles
, p. 1043 - 1044 (1997)
Ozone is a versatile reagent which is well adapted to solid phase synthesis: terminal double bonds can he efficiently converted into alcohols, aldehydes or carboxylic acids depending on the reaction conditions.
A ROUTE TO LARGE CARBOCYCLES USING AN ALICYCLIC CLAISEN REARRANGEMENT.
Cameron, Andrew G.,Knight, David W.
, p. 5455 - 5458 (1982)
A potentially general route to large carbocycles is described involving a Claisen rearrangement of silyl enolates derived from appropriate unsaturated macrolides.

Bhalerao, Uday T.,Sridhar, Madabhushi
, p. 4341 - 4342 (1993)
Photoexcited p-dimethoxybenzene catalyses oxidative cleavage of various alkenes to corresponding carbonyls in the presence of oxygen.
A General Approach to Intermolecular Olefin Hydroacylation through Light-Induced HAT Initiation: An Efficient Synthesis of Long-Chain Aliphatic Ketones and Functionalized Fatty Acids
Guin, Joyram,Paul, Subhasis
supporting information, p. 4412 - 4419 (2021/02/05)
Herein, an operationally simple, environmentally benign and effective method for intermolecular radical hydroacylation of unactivated substrates by employing photo-induced hydrogen atom transfer (HAT) initiation is described. The use of commercially available and inexpensive photoinitiators (Ph2CO and NHPI) makes the process attractive. The olefin hydroacylation protocol applies to a wide array of substrates bearing numerous functional groups and many complex structural units. The reaction proves to be scalable (up to 5 g). Different functionalized fatty acids, petrochemicals and naturally occurring alkanes can be synthesized with this protocol. A radical chain mechanism is implicated in the process.

Paragraph 0072; 0073; 0074, (2015/04/15)
The present invention provides a novel dihydroorotic acid dehydrogenase inhibitor which is applicable to various diseases. When used as an active ingredient, a compound represented by formula (I): (wherein X represents a halogen atom, R1 represents a hydrogen atom, R2 represents an alkyl group containing 1 to 7 carbon atoms, R3 represents -CHO, and R4 represents -CH2-CH=C(CH3)-R0 (wherein R0 represents an alkyl group containing 1 to 12 carbon atoms which may have a substituent on the terminal carbon and/or on a non-terminal carbon, etc.)), an optical isomer thereof or a pharmaceutically acceptable salt thereof has a high inhibitory effect on dihydroorotic acid dehydrogenase and can be used as an immunosuppressive agent, a therapeutic agent for rheumatism, an anticancer agent, a therapeutic agent for graft rejection, an antiviral agent, an anti-H. pylori agent, a therapeutic agent for diabetes or the like.
Palladium-catalyzed reduction of carboxylic acids to aldehydes with hydrosilanes in the presence of pivalic anhydride
Fujihara, Tetsuaki,Cong, Cong,Terao, Jun,Tsuji, Yasushi
supporting information, p. 3420 - 3424 (2013/12/04)
A palladium catalyst system that allows the reduction of carboxylic acids to the corresponding aldehydes with hydrosilanes as reducing agent and pivalic anhydride as an indispensable reagent has been developed. A simple mixture of commercially available bis(dibenzylideneacetone)palladium(0) [Pd(dba) 2], tri(para-tolyl)phosphane and methylphenylsilane realized the reduction of various aliphatic carboxylic acids as well as benzoic acids to aldehydes in good to high yields.
