The present invention relates to dryer-activated fabric softening compositions comprising: (A) fabric softening compounds; (B) a non-allylic perfume alcohol ester; and (C) optionally, (1) a carboxylic acid salt of a tertiary amine and/or a tertiary amine ester; and (2) a nonionic softener; wherein, preferably, the Iodine Value of the total number of fatty acyl groups present in (A), (C)(1), and (C)(2) is from about 3 to about 60. These compositions exhibit good antistatic properties as well as improved delivery from a substrate.

Highly stereoselective formation of cis-2-ene-1,4-diesters by homo- and heterocoupling of alpha-diazoacetates in the presence of Grubbs second-generation catalyst is demonstrated. The dual reactivity of the catalyst in alkene metathesis and diazocoupling has been exploited in the synthesis of 12-26-membered macrocyclic dienyl dilactones by one-pot carbene dimerisation/ring-closing metathesis.
