✦ Synopsis

Reductive coupling of ketones to form alkenes, an extremely useful synthetic process in organic chemistry, is most often achieved with the aid of low-valent titanium reagents, according to the procedure developed by McMurry."] It is generally accepted that this reaction involves the intermediacy of a titanium pinacolate, which is subsequently deoxygenated to the corresponding alkene in the rate-determining step (Scheme 1). The Scheme 1. Reductive coupling of ketones via a metalloplnacol intermediate g-> WILEY-VCH Verlag GmbH,

## Abstract The biologically active metabolite of vitamin D, 1,25‐dihydroxyvitamin D~3~ (1,25(OH)~2~D~3~) is a secosteroid whose genomic mechanism of action is similar to that of other steroid hormones and is mediated by stereospecific interaction of 1,25(OH)~2~D~3~ with the vitamin D receptor (VDR
