We describe an efficient convergent synthesis of vitamin D3 metabolites and analogues. The synthetic strategy relies on a tandem Pd-catalyzed A-ring closure and Suzuki–Miyaura coupling to the CD-side chain component to set directly the vitamin D triene system under protic conditions. This strategy enables rapid access to vitamin D3 and 3-epi-vitamin D3 metabolites and analogues modified at the side chain for biological evaluation and structural and metabolic studies.

The enantiomers of rotundial (1), a mosquito repellent from the leaves of Vitex rotundiforia, were synthesized from the enantiomers of limonene oxide (2). The absolute configuration of natural rotundial was determined to be R.
