An efficient one-pot synthesis of bis(phospholanes) was elaborated, which included a sequential Cp2ZrCl2-catalyzed cycloalumination of α,ω-diolefins with AlEt3, giving the corresponding bis(aluminacyclopentanes), and their in situ reaction with dihalophosphines to furnish the target α,ω-bis(phospholanes). The reaction of these compounds with H2O2 or elementary sulfur gave the corresponding bis(phospholane 1-oxides) and bis(phospholane 1-sulfides).
Cyclization of methyl-substituted 6-heptenyl radicals
Bailey, William F.,Longstaff, Sarah C.
, p. 2217 - 2219 (2007/10/03)
(Matrix presented) The behavior of a series of methyl-substituted 6-heptenyl radicals, generated from the corresponding iodides ((Me3Si)3SiH, AIBN in benzene at 80°C), has been investigated. The stereoselectivity of the 6-exo cyclizations, affording dimethylcyclohexanes, is low, and sizable quantities of methylcycloheptane, generated via 7-endo cyclization, are also produced.
SYNTHETIC INVESTIGATIONS INTO INSECT-ATTRACTING SUBSTANCES (SEX ATTRACTANTS). IV. SYNTHESIS OF 14-METHYL-8-cis-HEXADECENAL AND 14-METHYL-8-trans-HEXADECENAL, COMPONENTS OF THE SEX PHEROMONE OF THE DERMESTID BEETLE Trogoderma granarium EVERTS

14-Methyl-8-hexadecyn-1-ol was obtained by the alkylation of 7-methyl-1-nonyne with heptamethylene chlorohydrin.Its hydrogenation in the presence of colloidal nickel catalyst was used for the synthesis of 14-methyl-8-cis-hexadecen-1-ol, and reduction with lithium aluminum hydride was used for the synthesis of 14-methyl-8-trans-hexadecen-1-ol.Both ethylenic alcohols were converted by oxidation into the corresponding aldehydes, which are the main components of the sex pheromone of the dermestid beetle.
