efficient concise stereoselective total synthesis of cryptomoscatone D2 and syntheses of (5R,7S)-kurzilactone and (+)-cryptofolione, based on an asymmetric acetate aldol reaction starting from trans-cinnamaldehyde, are described. The other key reactions are a Horner–Wadsworth–Emmons reaction, a Brown’s asymmetric allylation and a ring-closing metathesis. An efficient concise stereoselective total synthesis
