A number of chiral propargylic and allylic alcohols were resolved by lipase-catalyzed kinetic resolution (Novozym 2 435). In some cases the enantiomeric excess was high (up to >99%). (C) 2004 Elsevier Ltd. All rights reserved.

Rieke zinc has been found to be a very selective reducing agent of alkynes to cis-alkenes, allowing for the reduction of enynes to 1,3-dienes, diynes to enynes or dienes, and of propargylic alcohols to cis-allylic
