Synthesis of 2-hydroxy-3-substituted naphthoquinones using the Heck reaction 

Pérez Sánchez, Alice Lorena; Lamoureux Lamontagne, Guy; Zhen-Wu, Bi Yun (2007-06)
An efficient Heck coupling of 2-hydroxy-3-iodo-naphthoquinone with a series of electron-deficient alkenes in aqueous solution has been accomplished. The method is characterized by simple conditions and facile work-up to ...

Reactivity and structure of derivatives of 2-hydroxy-1,4-naphthoquinone (lawsone) 

Lamoureux Lamontagne, Guy; Pérez Sánchez, Alice Lorena; Araya Marchena, Mario Esteban; Agüero Robles, Christian Gerardo (2007-11)
The structures of two derivatives of 2-hydroxy-1,4-naphthoquinone (lawsone) are examined using the density functional theory (DFT) hybrid functional B3LYP. Using the optimized structure of lawsone acetate, the reactivity ...

Structure, chirality, and field testing of a male-produced aggregation pheromone of Asian palm weevilRhynchophorus bilineatus (Montr.) (Coleoptera: Curculionidae) 

Oehlschlager, Allan Cameron; Prior, R. N. B.; Pérez Sánchez, Alice Lorena; Gries, Regine; Gries, Gerhard; Pierce Jr., Harold D.; Laup, Sam (1995-10)
4-Methyl-5-nonanol is a male-produced aggregation pheromone of the Asian palm weevil,Rhynchophorus bilineatus (Montr.). The pheromone was identified by coupled gas chromatographic-electroantennographic detection (GC-EAD) ...

Sex pheromone components of Diatraea considerata (Heinrich) (Lep., Pyralidae) 

Gries, Regine; Dunkelblum, Ezra; Gries, Gerhard; Baldilla, F.; Hernández, C.; Álvarez, F.; Pérez Sánchez, Alice Lorena; Velasco, J.; Oehlschlager, Allan Cameron (1998-08)
Three aldehydes. (Z)-11-hexadecenal (Z11–16:Ald), (Z)-7-hexadecenal (Z7–16:Ald) and (Z)-13-octadecenal (Z13–18:Ald), in a ratio of 74:23:3 are female-produced sex pheromone components of the pyralid moth, Diatraea considerata ...

Sudoku Puzzles for First-Year Organic Chemistry Students 

Pérez Sánchez, Alice Lorena; Lamoureux Lamontagne, Guy (2007-04)
We use sudoku puzzles to help the students (i) learn the correspondence between the names of the amino acids, their abbreviations, and codes and (ii) learn the correspondence between the names of the functional groups, ...

Aggregation pheromone of palmetto weevil, Rhynchophorus cruentatus (F.) (Coleoptera: Curculionidae) 

Weissling, Thomas J.; Giblin Davis, Robin M.; Gries, Gerhard; Gries, Regine; Pérez Sánchez, Alice Lorena; Pierce Jr., Harold D.; Oehlschlager, Allan Cameron (1994)
5-Methyl-4-octanol is the major aggregation pheromone of the palmetto weevil,Rhynchophorus cruentatus (F.). The pheromone (cruentol) was identified by coupled gas chromatographic-electroantennographic (GC-EAD) analysis of ...

Synthesis and biological evaluation of novel ferrocene–naphthoquinones as antiplasmodial agents 

García Barrantes, Pedro M.; Lamoureux Lamontagne, Guy; Pérez Sánchez, Alice Lorena; García Sánchez, Rory N.; Martínez, Antonio R.; San Feliciano, Arturo (2013-12)
This work deals with the synthesis and evaluation of new compounds designed by combination of 1,4-naphthoquinone and ferrocene fragments in a 3-ferrocenylmethyl-2-hydroxy-1,4-naphthoquinone arrangement. A practical coupling ...

Chemical and Behavioral Ecology of Palm Weevils (Curculionidae: Rhynchophorinae) 

Giblin Davis, Robin M.; Oehlschlager, Allan Cameron; Pérez Sánchez, Alice Lorena; Gries, Gerhard; Gries, Regine; Weissling, Thomas J.; Chinchilla López, Carlos Manuel; Peña, Jorge E.; Hallett, Rebecca H.; Pierce Jr., Harold D. (1996)
Palm weevils in the subfamily Rhynchophorinae (Curculionidae) (Rhynchophorus spp., Dynamis borassi, Metamasius hemipterus, Rhabdoscelus obscurus, and Paramasius distortus) use male-produced aggregation pheromones for ...

Optimization of semiochemical-based trapping of Metamasius hemipterus sericeus (Olivier) (Coleoptera: Curculionidae) 

Giblin Davis, Robin M.; Peña, Jorge E.; Oehlschlager, Allan Cameron; Pérez Sánchez, Alice Lorena (1996-08)
Response of adults of the West Indian sugarcane weevil,Metamasius hemipterus sericeus, to various semiochemical treatments and physical trap designs was studied in southern Florida in field-grown banana and Canary Island ...
