Remote and reversible! Phosphinites serve as reversiblybounddirectinggroups for the remotecontrol of the regio‐ and diastereoselectivehydroformylation of bishomoallylicalcohols (see scheme; r.r: regioisomer ratio). The distance between the double bond and the functional hydroxy group to which the directinggroup is reversiblybound is the longest ever reported.
The present invention provides non-peptide organic compounds that have a structure analogous to or reminiscent of the TMOF structure and have pesticidal activity. Thus the present invention concerns pesticidal compounds that inhibit digestion in pests by terminating or otherwise blocking synthesis of digestive enzymes by activating a TMOF receptor (collectively referred to herein as “pesticidal compounds”). The pesticidal compounds and other compounds of the present invention are usefully employed in the control of pests, particularly insect pests such as mosquitoes, which ingest blood.

A stereoselective polyene cyclisation cascade was enabled by using HFIP as a solvent. The process is triggered by a cation generated from an alcohol in situ and leads to the formation of three new C-C bonds and up to five new stereocenters as a single diastereomer. The cyclised products can be derivatised to obtain steroidal analogues in a single step.
