This disclosure relates to the field of molecules having pesticidal utility against pests in Phyla Nematoda, Arthropoda, and/or Mollusca, processes to produce such molecules and intermediates used in such processes, compositions containing such molecules, and processes of using such molecules against such pests. These molecules may be used, for example, as nematicides, acaricides, insecticides, miticides, and/or molluscicides. This document discloses molecules having the following formula (“Formula One”).
There is provided a compound of the formula (I′):
wherein x is a nitrogen or CRx, Rx is a hydrogen, etc., R
1
is an optionally substituted hydrocarbon group, etc., R
2
is an optionally substituted hydrocarbon group, etc., ring A is 5- to 8-membered heterocyclic ring, etc., and each of Y
1
, Y
2
and Y
3
is an optionally substituted carbon or a nitrogen, etc.; or a salt thereof or a prodrug thereof, which have CRF receptor antagonistic activity and use thereof.
facilitate for the first time the intramolecular aza- and oxa-Michael reactions of α,β-unsaturated carboxylic acids. The combination of an arylboronic acid with a chiral aminothiourea allowed for these reactions to proceed successfully in an enantioselective manner to afford the desired heterocycles in high yields and ee’s (up to 96% ee). The overall utility of this dual catalytic system was demonstrated by
