One-Pot Generation of Bicyclo[3.1.0]hexanols and Cyclohexanones by Double Interrupted Nazarov Reactions.

Chemistry (Weinheim an der Bergstrasse, Germany)

Gelozia S, Kwon Y, McDonald R, West FG.
PMID: 29444379
Chemistry. 2018 Apr 20;24(23):6052-6056. doi: 10.1002/chem.201800758. Epub 2018 Mar 26.

Organoaluminum-mediated double interrupted Nazarov cyclization to access bicyclo[3.1.0]hexanols via nucleophilic methyl attack followed by Simmons-Smith-type electrophilic cyclopropanation is reported. These alcohols can undergo ring opening to afford cyclohexanones or cyclohexenones, broadening the range of scaffolds available via interrupted Nazarov...

Methyl- and phenyl-substituted N-(ethoxycarbonyl)-2-azabicyclo[2.2.0]hex-5-enes 6 were reacted with NBS in wet DMSO to afford bromohydrins. Mixtures of unrearranged 6-exo-bromo-5-endo-hydroxy-2-azabicyclo[2.2.0]hexanes 7a,b and rearranged 5-anti-bromo-6-anti-hydroxy-2-azabicyclo[2.1.1]hexanes 8a,b were formed stereoselectively from the parent alkene 6a and 4-methyl alkene 6b. The 5-methyl alkene...

Highly Enantio- and Diastereoselective Synthesis of 2-Substituted 1-Bicyclo[3.1.0]hexanols.

Angewandte Chemie (International ed. in English)

Mizojiri R, Urabe H, Sato F.
PMID: 29711618
Angew Chem Int Ed Engl. 1998 Oct 16;37(19):2666-2668. doi: 10.1002/(SICI)1521-3773(19981016)37:19<2666::AID-ANIE2666>3.0.CO;2-K.

Useful intermediates in organic synthesis, optically active bicyclic cyclopropanols were difficult to prepare by existing methods. They can now be readily synthesized with high enantio- and diastereoselectivity from Oppolzer's N-acylcamphorsultams and [Ti(OiPr)

Thermodynamic and Dynamic Properties of Micellar Aggregates of Nonionic Surfactants with Short Hydrophobic Tails.

The densities and viscosities of binary aqueous mixtures of poly(ethylenoxide)hexanols [C6 H13 (OCH2 CH2 )m OH, C6 Em ] (m = 3, 4, and 5) have been studied in the micellar composition range. For the same surfactants the self-diffusion...

Stereoisomers and analogs of 14-methyl-1-octadecene, sex pheromone of peach leafminer moth,Lyonetia clerkella, L.

Journal of chemical ecology

Sonnet PE, Proveaux AT, Adamek E, Sugie H, Sato R, Tamaki Y.
PMID: 24301893
J Chem Ecol. 1987 Mar;13(3):547-55. doi: 10.1007/BF01880098.

The synthesis of the enantiomeric 14-methyl-1-octadecenes in >99% EE is described. Enantiomeric 2-methyl-1-hexanols were intermediates in the synthesis. The 1-alkene had been previously identified as the sex pheromone of the peach leafminer moth. Several closely related structures that have...

A new one-step strategy for the stereochemical assignment of acyclic 2- and 3-sulfanyl-1-alkanols using the CD exciton chirality method.

The Journal of organic chemistry

Weckerle B, Schreier P, Humpf HU.
PMID: 11722220
J Org Chem. 2001 Nov 30;66(24):8160-4. doi: 10.1021/jo010768h.

A new one-step strategy is described for the stereochemical assignment of acyclic 2- and 3-sulfanyl-1-alkanols using the CD exciton chirality method. Using the 9-anthroate chromophore for the derivatization of both functional groups, the resulting bisignate CD curves unequivocally allow...
