The generality of the [CpCoL 2 ]-mediated [2+2+2] cycloaddition of α,ω-diynes to (cyclo)alkenes has been extended to include linear oligocycles as models for the one-step, A + D → ABCD construction of optically pure, novel 6,10-dihydroanthracycli

Enol ethers 1a-f are brominated at -78 o C and the resulting alkyl 1,2-dibromoethyl ethers are regioselectively coupled with propargylmagnesium bromide to give 4-alkoxy-5-bromo-1-pentynes 2a-f, which are protected at the acetylenic terminus with a tr

A variety of chiral, nonracemic 2-alkoxy-1-alkynylcyclopropanes 7 were synthesized in good to very good yields from enantiomerically pure glycidol derivatives (glycidol tosylate, epichlorohydrin) by boron trifluoride promoted addition of lithium trim

Organometaliic compounds may be extremely useful intermediates in organic synthesis in a number of ways. In fact, with the help of metals and metal complexes one can bring about transformations, which cannot otherwise be achieved.[1] In this respect,
