A borocyclopropanation of (E)- and (Z)-allylic ethers and styrene derivatives via the Simmons-Smith reaction using a novel boromethylzinc carbenoid is described. The carbenoid precursor is prepared via a 3-step sequence from inexpensive and commercially available starting materials. This methodology allows for the preparation of 1,2,3-substituted borocyclopropanes in high yields and diastereoselectivities. Several postfunction-alization reactions were also performed to illustrate the versatility of these building blocks.
Synthesis of combretastatin D-2. An efficient route to caffrane macrolactones

Combretastatin D-2, (1), was synthesized via a 10 step sequence. Macrolactonization was performed saturated substrate 12 in high yield and the double bond was established via dehalogenation of intermediate 15.
