Acyl Any group or radical of the form RCO- where R is an organic group; An example of the acyl group is the acetyl group Alkyl Any of a series of univalent groups of the general formula CnH2n+1 derived from aliphatic hydrocarbons Common Curiosities What is the primary structural difference...
pyran derivativesThe title rearrangement of the compounds (I) is influenced by the substituents at C-2. In the case of (Ia)-(Ic) the products (III), (V) and (VII) are formed via 1,2-bond shifts involving alkyl- or acyl-group migrations....
Is alkyl group a substituent? In chemistry, alkyl is a group,a substituent, that is attached to other molecular fragments. For example, alkyl lithium reagents have the empirical formula Li(alkyl), where alkyl = methyl, ethyl, etc. What is the difference between alkyl and acyl group? The ma...
摘要: Vinylsilanes are formed in high yields in the reaction of representative acyl(trimethyl)silanes with anions generated from Kocienski's sulfones.关键词: organo‐silicon compounds rearrangements DOI: 10.1021/ol034606e 被引量: 87 年份: 2003 ...
The key structural feature recognized by PAF-AH in phospholipids is the length and type of acyl group esterifying thesn-2 position of the glycerol backbone (Fig. 3). While PAF, which contains an acetyl group at thesn-2 position, is efficiently hydrolyzed, restriction...
However, fungicidal activity was higher at meta-substituted methyl group and meta-substituted chlorine atom. When trifluoromethyl group was on the benzene ring such as compounds IV-15 and IV-16, fun- gicidal activity was the highest. Second, for alkylacyl chloride (IV-18~IV-23), fungicidal ...
One-pot,three-component condensation of aroylthiourea,primary amine and alpha-halocarbonyl derivatives for the synthesis of 2-acylimino-3-alkyl-3H-thiazoline derivatives is described.This method is useful for simultaneously incorporating diverse functional groups at four positions in the 3H-thiazoline ske...
The bases 4 added carbon disulfide and acyl isothiocyanates with cleavage of the original ring to give derivatives of 1,2,4-dithiazoles 5 , 6 , and added isocyanates, alkyl and aryl isothiocyanates, carbodiimides, and nitriles to ... J Goerdeler,Wilfried L?bach - 《European Journal of Ino...
Acyl derivatives of amidopropanediol 12 wherein R12, X, and Y are as hereinbeforedescribed are prepared by treating 12 with an alkanoic acid anhydride under the conditions for the conversion of 6 to 15. To prepare a 1-alkenyl-2-amino-1,3-propanediol 17 wherein W, X, and m are as ...
A“derivative” of a compound refers to a chemical compound that may be produced from another compound of similar structure in one or more steps, as in replacement of hydrogen by an alkyl, acyl, or amino group. The term “pharmaceutically acceptable carrier” includes any of the standard pharm...
