3-indolylmethyl; Alk is C1-6 alkyl or C2-6 alkenyl and n = 0 or 1; R7 is H or R10CO where R10 is C1-4 alkyl, (C1-4 alkyl)aryl, C3-6... Montana,D John,O Jonathon,... 被引量: 0发表: 0年 Indolyl‐3‐Piperidinomethyl Ketone 30256‐73‐6 Indolyl‐3‐Piperidinomethyl Ketone...
This invention relates to a process for producing N-aryl-2-lactams and N-cycloalkyl-2-lactams by reductive amination of lactones with aryl amines utilizing a metal catalyst, which is optionally supported. LE Manzer - US 被引量: 2发表: 2004年 Reductive Amination of Aldehyde and Ketone with Am...
Aromatic-alkyl ketones are reacted with from 0.1 to 50 mol percent of an alkyl nitrite to form the corresponding aryl-α-oximinoketone which is then extracted from the reaction mixture and recovered. Consumed ketone can then be replenished and again reacted with alkyl nitrite.DORLARS ALFONS...
(Table3). Initially, acyclic tertiary alkyl bromides were examined. We were pleased to find that tertiary alkyl centers containing primary alkyl bromides, aryl, esters and ketone functional groups were compatible with the reaction conditions and afforded their corresponding products (5a–5k) in good...
The process forms an alkyl aralkyl ketone from an aralkenyl secondary alcohol having an allylic double bond relative to the hydroxycarbinyl group, and having the allylic double bond positioned between the aryl moiety and the hydroxycarbinyl group. This is accomplished by heating the alcohol in a...
Fungicidal compounds of the formula: ##STR1## wherein R is alkyl, alkenyl or alkynyl having up to 6 (preferably up to 4) carbon atoms, substituted or unsubstituted aryl (e.g. phenyl), substituted or unsubstituted aralkyl (e.g benzyl), cyano, alkoxycarbonyl or trihalomethyl (e.g. tr...
Here, we show a deacylative annulation strategy for preparing a large variety of aromatic-fused rings from linear simple ketone precursors. The reaction starts with homolytic cleavage of the ketone α C–C bond via a pre-aromatic intermediate, followed by a radical-mediated dehydrogenative ...
